Not yet registered and want to do the 2 day challenge?

When you register for the marathon, half or urban 10 miler there is a now a question on the registration page asking if you’d like to do the 2 day challenge.

Relay – as most of your runners aren’t on the registration site,  this question is not part of the registration form.   Instead, Captains and team runners can go to this form and add the 5K.    We’ll remind you when we remind captains by email about having relay runners sign the waiver.    Captains you just forward the email to your runners.
