Welcome to the team!

Now for the logistical stuff. 

First things first, all racers, regardless of which race you choose, need to get registered and pay your registration fees.

Once again, the race organizers are allowing discounted registration fees for the 5K, which means great savings for families and groups; and for individuals who receive free and reduced lunch and/or Medicaid (income-sensitive).

The table below details the fee structure for the 5K only. Please determine which levels are appropriate for your needs, and use the button below to enter your registration(s)

If you need any assistance, please contact Eryn Hoerig at (303) 232-1338 or
