Hi, I'm Coach Morgan, and today I'm going to answer the question, can I ride a mountain bike in a triathlon? If you've watched triathlon on TV, you've probably seen athletes riding road style or time trial style bicycles, usually not mountain bikes with thick wheels. However, you might be surprised to know that at your local sprint and Olympic distance triathlons there are plenty of athletes sporting plain old fashion mountain bikes. Today I want to go over the rules for actually selecting a bike to use in your triathlon, and what does or doesn't work for USA Triathlon sanctioned races. It's a big commitment to buy a road bike or a trial bike before your first triathlon, and if it's not in the budget, no worries, it's not required. The only rules that USA Triathlon has for their races is that the bike be in good working order, have two wheels and a working break system. That can either be a handlebar based brake system, or a brake system that simply requires a backwards pedal, such as a fixed gear bike might have. Should you be using an older mountain bike, I strongly recommend taking it to your local bike shop in advanced, just so that they can give it a thorough once over before race day. While USA Triathlon requires to bring your bike in good working condition pre-race, there's not really anyone there on race day to check it, so it's your responsibility to make sure that you don't suffer from unfortunate situations when you're out on the bike course on race day. Don't be afraid to take your old mountain bike out for your first tri, you'll be in good company. The most important thing is to have fun and have a successful day.
