About

The TYathlon takes place in Mahopac on September 18, 2027. The sprint triathlon starts at 7:00 a.m., for individuals and relay teams, with a 0.3-mile (0.5 km) swim, a 10.5-mile (16.9 km) bike and a 5K (3.1-mile) run. A stand-alone 5K run is also offered at 9:30 a.m.

The sprint is the most accessible triathlon format: the swim is short, the bike leg takes less than an hour for most participants and the run is a 5K. What surprises beginners most is the bike-to-run transition, when the legs respond poorly for the first few minutes; a few short brick sessions in training are enough to get used to it. The relay option lets three people split the disciplines according to their strengths.
