New to triathlons? Or just want to improve in the water, on the bike or with the run? Start here with CIRCUIT25’s Trinity Regiment.
Classes meet three times a week, with each class being devoted to an individual activity: swimming, biking or running.
SWIMMING: We work on stroke, breathing and balance. We have four one-on-two swimming sessions each week to give you the attention needed before doing our group swimming training.
BIKING: We collaborate with highly qualified bike specialists to assist you in fitting, sales and proper gear so that you’re given the best experience possible when racing and transitioning.
RUNNING: Our trainers focus on the last and toughest leg of triathlons by pushing you as hard as the race will in order to strengthen your road legs, stamina and grit.
At the end of the six weeks of training, we’ll help you sign up and make it through your first race.
Please note that these classes are not only for beginners. If you’re a seasoned triathlete looking to increase your endurance, strength, transitioning and time, then C25’s Trinity Regiment is perfect for you. At Circuit25, we help you reach your personal best. Send us an email for more information and you’ll cross that finish line in record time.
