How do I create or join a team?
After you register as an individual Road Bike participant, you have the option to create a team of at least 4 riders. Each team can compete against other teams for the best combinedtime up the mountain. To make a team during your registration, create a team name under the “Event Questions.” Next, indicate whether it is an all male, an all female or coed team. A coed team must have a minimum of two males and two females. Then, choose whether your team is in the “Teams/Club” or the “Friends/Family” category. Finally, tell your friends to look for and join your team when they register.
Number of Team Members
You can have as many team members as you like on your team but only the top 4 finishers' times will be used to determine the “combined time” for your team up the mountain. Note that the combined time for coed teams will be determined by the time(s) of the first 2 men and the first 2 women on your team to cross the finish line.
You will have the option of starting in the same wave as your team members. If you select this option, you will be placed in the wave that corresponds to the slowest time registered for all of your team members. If you do not select this option, you will be placed in the wave corresponding to your individual estimated time.
Is it required that I ride with a Team?
