Duathlon Underground Winter MTB Duathlon

To keep you motivated to train this winter Duathlon Underground will be hosting a frosty run bike run event this December at Big Walnut Sports Park in Greencastle Indiana.

The runs will be on the paved trail around the park and the bike will be on lightly traveled country roads.

Please note you must use a mountain bike for this event! It is on the road but with an MTB the speeds will be slower and hopefully warmer!

We wont be charging to sign up on this website but you will be required to bring $20.00 the day of the race to compete. We’re doing this just in case the weather is too bad for a safe race negating the need to issue refunds etc…..

We will send out an email the week of the race to confirm that the race is happening as long as weather is suitable.
