To keep you motivated to train this winter Duathlon Underground will be hosting a unique run bike run event  March 6th at 3 Fat Labs event center located West of Greencastle Indiana.

As the title says, you will be crossing two historic 1800's covered bridges as well as passing by a cemetery founded by relatives of the famous Daniel Boone.

The two runs are totally on gravel and the bike is part gravel and part pavement with some nice hills to keep you honest.

Distances are 2 mile run/ 10 mile bike/ 2 mile run.

Please note we suggest you use a mountain bike for this event. The gravel in March can be a bit sloppy and a road bike will definitely not work.

Overall male and female awards as well as ten year age group awards will be handed out after the race.
