Start a Team!

Sign up with your friends and running buddies! We will take the combined time of your Fastest 5 finishers to calculate Team Awards. Sign-up as many team members as you want and improve your odds of winning. Ask your Team Captain to enter your Team Name when he/she registers. Individual members will select your Team Name from the Pull-Down Menu in the Team Registration field. This is a LIVE event (only), and we look forward to watching the competition.
