Winter is base season
Indoor trainer and treadmill sessions, pool swims, and strength work build your aerobic engine through the cold months without depending on the weather.
Northeast triathlon coaching
Foundry Athletics Co. coaches triathletes and endurance athletes across the USA from its home in Bethlehem, Pennsylvania, in the Lehigh Valley. If you train in the Northeast, you get a coach who knows the region's seasons and races, plus in-person group sessions if you're close to home base.
Built for the region
Training here means short winter days, cold early-season water, and a race calendar packed into a few months. If that's your reality, your plan is built for it.
Indoor trainer and treadmill sessions, pool swims, and strength work build your aerobic engine through the cold months without depending on the weather.
Cold early-season water is planned for, with wetsuit swims, sighting practice, and race-specific bricks completed before your first race.
Most Northeast racing runs from late spring to early fall. Your season is planned so you peak for key races and recover well between them.
