This year we aim to have 72 athletes participating with a wide variety of triathlon experience. This event is great for beginner triathletes looking to try a triathlon without having all of the gear (i.e. wetsuit, bike) and triathletes looking for a hard workout or event to train for. The event is put on by MIT Recreation and the MIT Triathlon Club Team in Cambridge, MA and takes place entirely indoors at the Alumni Pool and Wang Fitness Center (Building 57, 6 Vassar St).

Format: The triathlon will be a timed event; scores will be based on how much distance each participant covers in a specific amount of time. Transitions will be included for each heat making each heat a total of 75 minutes. See breakdown below:

•Swim: 15 minutes in a 25 yard lap pool
•Transition 1: 10 minutes to change in locker room
•Bike: 25 minute bike on Schwinn Z bike (2nd floor spin studio)
•Transition 2: 5 minutes to transition
•Run: 20 minute run or walk on Matrix or Precor treadmills (1st floor fitness area)
