You know that feeling. Your friend has been training for months for this big marathon. They talk about it non-stop. They bought special shoes, special shorts, and even special socks. Now they want you to stand on the side of the road for hours to cheer them on. What do you do? You make the funniest sign ever, that’s what! A funny sign won’t just make your runner smile—it might be the exact thing they need to keep going when their legs feel like jelly and their brain is screaming “take a nap!”
I’ve been to more marathons than I can count (mostly because I can’t count very high). Trust me when I say that runners LOVE funny signs. They’re stuck running for hours, and a good laugh can make all the difference. Plus, other spectators will think you’re a comedy genius, which is always a bonus.
Funny Things to Write on Marathon Signs
Making someone laugh when they’re in pain is a true gift. Here are 30 sign ideas that will have runners snorting with laughter as they zoom (or shuffle) past you.
1. “Run Like You Left The Stove On”
This sign plays on that sudden panic we all feel when we think we’ve made a huge mistake. It gives runners a funny mental image of rushing home to stop a disaster. The urgency might even help them pick up their pace!
Many runners hit a mental wall during races. A sign like this cuts through the fog with humor and gives them a silly but motivating reason to keep moving fast. It works best early in the race when runners still have energy to laugh.
2. “If Marathons Were Easy, They’d Be Called Your Mom”
This cheeky sign pokes fun at “your mom” jokes while giving runners a boost. It reminds them that they’re doing something truly challenging—something to be proud of. The surprise twist on a familiar joke format makes it extra funny.
Best used around mile 20 when runners are questioning their life choices. The sudden laugh can snap them out of their pain for a moment. Just be ready for some eye rolls along with the chuckles!
3. “Chuck Norris Never Ran A Marathon – He’s Scared of You”
Everyone knows Chuck Norris jokes. This sign flips the script by making the runner the tough one. It gives them an instant ego boost during a time when they might be feeling weak.
The absurdity hits just right. Instead of another Chuck Norris fact, you’re telling the tired, sweaty runner that THEY are the legend now. Place yourself around mile 15-18 where runners start to doubt themselves and need a confidence boost.
4. “You’re Running Better Than The Government”
This sign works on multiple levels. First, it’s a compliment to the runner. Second, it’s a gentle political joke that doesn’t target any specific party. Third, let’s face it—most things run better than the government!
Political humor gets people laughing because it taps into shared frustrations. But this joke stays light enough that it won’t upset anyone during their race. It’s perfect for any point in the marathon since the truth of it never changes.
5. “Smile If You’re Not Wearing Underwear”
This naughty-but-not-too-naughty sign catches runners off guard. Many runners go commando to avoid chafing, making this sign hilariously relevant. You’ll see plenty of guilty smiles and maybe even hear some laughs.
Funny thing is, even runners who ARE wearing underwear often smile at this one. The unexpectedness makes it work! Hold this sign where there are lots of spectators so you can enjoy the reactions from both runners and crowds.
6. “This Parade Is Taking Forever”
This sign jokes that the marathon is actually just a really slow parade. It playfully downplays the incredible athletic feat happening, which is funny because it’s so obviously wrong. Runners appreciate the absurdist humor.
The sign works because it pretends not to understand what’s happening. This fake confusion about a major event is a classic comedy technique. It’s best placed early in the race when runners still have the energy to appreciate the joke.
7. “Your Feet Hurt Because You’re Kicking So Much Butt”
This sign delivers a compliment disguised as an explanation for pain. Runners are definitely hurting, but this reframes their suffering as evidence of how awesome they are. The play on words makes it both encouraging and funny.
Using this around mile 18-20 gives runners a new way to think about their pain. The unexpected positivity helps them push through the toughest parts of the race. Plus, who doesn’t want to think they’re kicking butt?
8. “Worst Parade Ever”
Similar to #6 but even shorter and more blunt. This sign’s humor comes from its brevity and the absurd complaint. By pretending to be disappointed by the “parade,” you’re acknowledging how tough marathons are while keeping things light.
The sign gives tired runners a mental break with a quick laugh. They don’t need to think too hard to get the joke, which is perfect when they’re hitting the wall. This works great anywhere after the halfway point when the fun of running has definitely worn off.
9. “Run Faster, I Just Farted”
Bathroom humor never fails, especially during a marathon where bodily functions are top of mind for runners. This sign is silly, unexpected, and gives a fake “reason” to speed up. The mental image alone is enough to crack a smile.
What makes this sign extra funny is how it pretends to make their speed about YOU rather than their race goals. This shift in perspective offers a moment of comic relief. Place this sign on a stretch where runners might be slowing down.
10. “If Trump Can Run, So Can You!”
This political joke works for people on all sides. It plays on the double meaning of “run” – for office and in a race. Without taking a strong political stance, it still gives runners a chuckle and some motivation.
The beauty of this sign is its simplicity and how it connects current events to the marathon. It’s best placed at a point where runners need a bit of motivation, like around miles 12-15 when they’re starting to get tired but still have a long way to go.
11. “That’s Not Sweat, It’s Your Fat Crying”
This sign makes runners laugh by reframing their hard work in a new, funny way. It suggests they’re accomplishing their fitness goals right before everyone’s eyes. The personification of fat as something that can cry makes the joke work.
For maximum effect, hold this sign between miles 15-20 when runners are really sweating. The joke lands better when they’re visibly drenched. Just be careful with this one – it works best for races where most participants are running for fitness goals.
12. “You Paid Money For This?”
This sign points out the funny truth that runners voluntarily paid to put themselves through this pain. It’s both a question and a statement of disbelief that anyone would choose this suffering. Runners can laugh at themselves and their questionable life choices.
The sign works because it states what many runners are secretly thinking. Place this around mile 21-22 when runners are truly suffering and questioning all their decisions. The shared moment of “What was I thinking?” creates an instant connection.
13. “If You’re Reading This, You’re Not Last”
This sign offers a funny kind of encouragement. It points out that the runner is at least beating SOMEONE in the race – whoever is behind them. For middle and back-of-the-pack runners, this can be a motivating little joke.
The sign works because it sets a very low bar for success. Instead of pushing for a personal best, you’re just telling them not to be last! This realistic, low-pressure approach often gets a laugh. Place this sign in the second half of the course.
14. “You Look So Much Better Than The Guy Behind You”
This backhanded compliment makes runners laugh because it’s not really saying they look good – just better than someone else who probably looks terrible! The comparison creates the humor while still being somewhat encouraging.
The sign plays with expectations. What starts as a compliment takes a turn that acknowledges how rough everyone looks during a marathon. This works best in the late stages of the race when everyone truly does look rough!
15. “Chafing Is Sexy”
This sign tackles a non-glamorous running problem in a hilariously inappropriate way. Chafing is a universal marathon issue that’s rarely talked about in public. Making it “sexy” creates a funny contradiction that runners will appreciate.
The best place for this sign is around miles 15-20 when chafing is likely becoming a real problem. The unexpected take on their discomfort gives runners something to laugh about instead of focusing on the pain. The absurdity provides a perfect mental distraction.
16. “Your Training App Lied To You”
Most runners use apps that promise to prepare them for race day. This sign playfully calls out how those apps often underestimate how hard marathons actually are. The truth of this statement is what makes it funny.
Runners can relate to the feeling of “I thought I was ready, but THIS is crazy!” This shared experience creates an instant connection. Hold this sign around miles 18-22 when the reality of the marathon challenge is fully sinking in.
17. “This Is A Lot Of Work For A Free Banana”
Marathons often give out bananas at the finish line. This sign points out the absurd exchange rate of running 26.2 miles for a piece of fruit. The huge mismatch between effort and reward creates the perfect joke.
What works about this sign is how it reduces the grand achievement of marathon completion to the most trivial of the rewards. Display this in the later miles when runners are wondering if all this effort is worth it. The banana becomes a funny symbol of their questionable decision-making.
18. “Your Pace Or Mine?”
This sign creates humor by using a dating pickup line in the context of a marathon. The double meaning plays on “pace” as both a running term and a suggestion to spend time together. The unexpectedness makes runners smile.
By turning something athletic into something flirty, you create a funny cognitive shift. This works well in the first half of the race when runners still have enough mental energy to catch the joke. It’s a light, fun sign that breaks the tension of competition.
19. “Toenails Are Overrated Anyway”
Long-distance runners often lose toenails due to the repeated impact. This sign acknowledges this gross reality in a casual, funny way. It normalizes a strange side effect that many runners experience but don’t talk about publicly.
The humor comes from treating something alarming (losing body parts) as no big deal. Place this around mile 24-26 when runners are near the end and have likely been feeling their toenails in jeopardy for quite some time!
20. “Keep Going, My Arms Are Tired From Holding This Sign”
This sign hilariously compares your minor discomfort to their major one. The false equivalence between holding a sign and running a marathon creates instant comedy. It’s so absurd that runners can’t help but laugh.
The comparison is so outrageous that it gives runners perspective on their achievement. Place this sign in the later miles (20+) when runners really are tired and struggling. The joke reminds them that what they’re doing is truly exceptional.
21. “Free Beer (Just Kidding, Keep Running)”
This sign cruelly gets runners’ hopes up before dashing them immediately. The emotional roller coaster of excitement and disappointment creates the humor. Don’t worry – runners will forgive you because the joke is so relatable.
The effectiveness comes from targeting something runners might actually want badly during the race. The fake-out acknowledges their suffering while giving them something to laugh about. Place this after mile 20 when runners would truly do anything for a beer.
22. “You’re Beating Everyone On The Couch”
This sign reminds runners that regardless of their pace, they’re doing better than all the people who didn’t even try. It’s funny because it’s both encouraging and sets an extremely low bar for comparison. The mental image of racing against couch potatoes adds to the humor.
What makes this work is how it reframes success in a way that guarantees they’re winning at something. Hold this sign around miles 15-18 when runners might be getting discouraged about their performance. It gives them a new way to feel accomplished.
23. “Run Like Someone Just Called You Jogger”
Serious runners often hate being called joggers. This sign plays on that pet peeve, suggesting they should run faster to prove they’re “real” runners. The insider humor makes runners feel seen and understood while giving them a laugh.
The sign works because it taps into the funny culture and identity of running. It’s like an inside joke that creates community. This sign is effective anywhere, but particularly good in spots where runners might be visibly slowing to a “jog.”
24. “Pain Now, Wine Later”
This sign offers a funny reminder of the reward waiting at the finish line. The rhyme makes it catchy, and the promise of alcohol makes the suffering seem worthwhile. It acknowledges the pain while keeping things light.
The effectiveness comes from giving runners something concrete to look forward to. Rather than abstract accomplishment, you’re promising wine! Place this in the tough later miles (18+) when runners need strong motivation to continue through the pain.
25. “Nice Stamina… Call Me”
This suggestive sign makes a flirty joke about running endurance having other applications. The double meaning gives tired runners something to smile about. The unexpectedness of romantic humor in a sports context creates the comedy.
What makes this sign work is how it turns their athletic ability into something with social benefits. Hold this around miles 10-15 when runners still have enough energy to appreciate the joke but are definitely showing their stamina.
26. “All Toenails Go To Heaven”
This sign acknowledges the sacrifice of toenails in marathon running with mock religious reverence. The personification of toenails as having souls creates an absurd mental image that’s sure to make runners laugh through their pain.
The humor comes from treating this minor physical consequence with extreme seriousness. Place this sign in the final miles (22+) when toenails are likely already feeling the effects of all those miles. The absurdity provides a welcome mental break.
27. “Morticians Love Marathoners – Great Hearts, Terrible Knees”
This darkly funny sign compliments runners’ cardiovascular health while acknowledging the joint damage from running. The morbid professional perspective creates unexpected humor that catches runners off guard.
What makes this sign effective is how it wraps a health truth in dark humor. It’s both a compliment and a warning all at once. Place this around mile 18-22 when many runners are feeling the knee pain that proves the sign right!
28. “Don’t Stop – People Are Watching”
This sign plays on social pressure in a funny way. It reminds runners that they have an audience and jokingly suggests they should be motivated by potential embarrassment. The light psychological manipulation makes runners smile.
The humor comes from pointing out the performers’ relationship between runners and spectators. This sign works best at spots where runners might be tempted to walk or even quit. The gentle push often gets a knowing smile or even a renewed burst of energy.
29. “If You Collapse, I’ll Pause Your Garmin”
Runners are often obsessed with tracking their runs and hate when they forget to stop their watches. This sign shows you understand this quirk while making light of the possibility of medical emergency. The misplaced priorities create the comedy.
The joke works because it treats the tracking device as more important than the person. Place this sign in the later miles (20+) when medical incidents are more likely to occur. The dark humor gives runners a mental break from their suffering.
30. “You’ve Got Stamina… Want My Number?”
This flirty sign compliments runners’ endurance with romantic implications. Similar to #25 but more direct, it suggests their athletic ability makes them attractive. The unexpected context shift from sports to dating creates the humor.
What makes this effective is turning their suffering into something positive and desirable. It’s a boost to both their motivation and ego. Place this sign in the later miles (18+) when runners need encouragement and assurance that all this effort has value!
