VDOT Challenge

Virtual Racing Series

Times have changed but our competitive fire and desire to self-improve still burns bright. We're introducing a new way to race the global running community using VDOT O2.

The VDOT Challenge is a virtual racing series occurring every two weeks in 3-day blocks (Friday, Saturday, Sunday); results are posted on a Monday following each Challenge.

When using VDOT we're all in the same race regardless of the distance you choose to run.
