FAQ

What type of shoes, clothing and gear should I wear?

Shoes: Here is what we see most. The racers that have lots of cycling experience and have bike shoes with cleats will typically switch shoes during the race for each event. Others choose to do the entire race in their running shoes and regular bike pedals. You will obviously have a quicker transition without switching shoes, but probably a slower bike leg if you are doing it in running shoes vs. cycling shoes (provided the bike leg is long enough and fast). What you choose on race day is up to you, as you consider a combination of your cycling ability, the terrain & trail conditions. Clothing: In the shorter races, no one takes time to change clothes. Most racers will wear what we call a triathlon short with a thin pad. Richardson Bike Mart carries them if you live in the Dallas area, and they’re surely happy to mail you a pair. That is not to say you can’t race in something else. Some racers compete in running shorts, or gym shorts, or cycling shorts. For a short race, you can do almost anything but the tri-shorts will leave you in the best condition after the race. I’ve even seen a superman and batgirl costume at a race. For the upper body, the women typically wear jog bras and a technical fabric shirt that breathes well, or a t-shirt. The guys will also wear either a technical fabric shirt or a t-shirt. If it is cooler temperatures, be prepared with either tights or knee warmers for your legs, full finger cycling gloves, and a long sleeve technical fabric shirt that breaths well for your upper body and that has sleeves that can easily be pushed up if you get hot. Also consider layers when it is cooler temperatures and light jackets for wind or rain. Remember, once you start racing you’ll warm up fast. Note: You might want check out our Facebook page and look at the albums to get an idea of what the racers are wearing, how the race looks and just what all is going on. We hope you’re enjoying our races and feel free to contact us if you have a question.

How does the race work and what happens to all my gear while I am racing?

We have a transition area roped off that you will place all your belongings in. Some teams will bring blankets, or a mat to mark their territory (within reason) within the transition area. It is first come, first serve, the morning of the race as to where you pick your transition area within the boundaries of the roped off area. There is a specific entry and exit to the transition area with a lane down the middle. Bikes must be walked through transition at all times. You are responsible for having enough fluids and food for the length of the race. No outside support is allowed once the race starts. You will go through transition between each leg of the race.

Where does the exchange take place for relay teams?

The exchange will take place within the transition area between each event.

What type of bike must I use?

All racers must ride a mountain bike or mountain biased hybrid. You must also have a CPSC approved helmet.
