The great debate: Bike vs Triathlon shorts

Posted Mar 09 2011 9:40am


Bike shorts Who wants to run a marathon in a diaper?  That’s what you’re potentially doing if you wear bike shorts to run an Ironman.

The debate rages on about using bike shorts versus triathlon specific shorts for triathlons.  Sure, you have some extra padding for a 112 mile bike ride, but that extra padding takes extra time to dry out after the swim and any sweat from the bike ride will collect in that pad as well, so when you hit the run you’ll be contenting with jelly-legs AND diaper rash. 


Extra Padding
Specifically Designed for Biking
More Comfort Over 112 Mile Bike Ride
Good Grip for Non-Slip on Legs


Extra Padding Collects Extra Moisture
Extra Padding Can Cause Extra Chaffing Even When Dry
Not Designed for Running and Swimming
Advantage of Comfort Diminishes When Bike Distance is Shorter
Too Much Grip for Non-Slip When Running


Designed with All Three Sports in Mind
Reduced Padding Allows for Easier Running and Swimming
Less Chaffing On Runs
Less Fluid Retention in Pad


Less Padding and Comfort for Longer Bike Rides
Shorter Than Bike Shorts, May Ride Up Leg More
Thinner Materials May Result in Lesser Product Life

As you can see, each has a plus and a minus.  Bike shorts are a great tool for long training rides so save your rump, but if you don’t train in clothes you will race in, you may be in for a rude surprise when you exit T2 and realize you had less padding for 112 miles.  Ouch.

Consider using bike shorts for the winter training rides.  Most of us have to relegate ourselves to the basement spinning on the trainer and need all the help we can get to get through hours of riding nowhere.  I sore backside adds to the disparity of riding a trainer all winter.  Some triathlon shorts are a little more delicate and riding for hours a week can deteriorate them and result in spending more money to keep up your tri short supply, or you’re riding in threadbare shorts exposing your assets.  Take into account the harsh chemicals in pools as well and avoid using tri shorts while training in pools.

In summary, you can survive triathlons in bike shorts, I have for years.  But, if you are getting more competitive and challenging yourself with larger distances, triathlon specific shorts are the way to go.  You won’t fight extra padding on the swim, you may sacrifice some comfort on the bike, but it will pay for itself over the run when you aren’t fighting a diaper and chafing your way to the finish line.
