"Pick 6" Registration 


Our very popular "PICK 6" is great for those runners that want to run multiple events with the ERS, but don't have the schedule to join us in a Season Pass.

How it works:

  • Choose any 6 events you want...
    • All Colorado or a mix of Colorado and California races
  • Choose a Race Distance for each event
  • Receive an automatic 25% off your total registration at check out
  • Receive 1 Confirmation number
  • Automatically signed up for each event you chose, no additional paperwork 

"Pick 6 " prices may vary based on which races and distances you choose to participate in.


We do offer a Shirt and "No Shirt" registration option to each of our events.

ALL pre-registered runners will receive a gender specific T-shirt upon packet pickup. When registering for your event online you will have the opportunity to select the correct shirt size. (If you choose the shirt option)

Important- Only those people that PRE-register for an event and select the shirt option will be guaranteed to receive a T-Shirt with their registration, while ALL packet pickup and race day registrations will be asked to wait until they have finished the designated event to pick up their race shirt. Please note, that race day registrants will not be guaranteed the correct size shirt if any at all. Thank you for understanding this policy, as we want to make sure those runners that register early do receive the shirt they requested.   We order our shirts about 10 days out from the respective event, so it is our recommendation that you complete online registration no later than that time frame to be guaranteed a shirt of your choosing.

ALL FINISHERS, regardless of distance will receive a medal.

If you register for a specific race distance and need to upgrade or downgrade, you may do so by contacting our staff before the registered event. 

  • $30 Upgrade Fee is required for 10k to Half
  • $15 Upgrade fee is required for 5k to 10k
  • No refunds will be given for downgrading
