Register for the Mammoth Half Marathon or Mammoth 5K as a virtual runner!  As a virtual runner, you won’t miss out on amazing perks to keep you motivated during your training runs.  Your bib, official shirt, and finisher medal (plus the Challenge Spinner Medal if you participated in the San Diego Half Marathon) will be mailed directly to your domestic address on file.

While we will definitely miss you at the actual start line, we want to reward your half marathon or 5K accomplishment anytime you are able to get it done.  <Virtual hi fives all around!> #mammothhalf
