Lake Terramuggus Sprint Triathlon #2

The Lake T Sprint Series has been the first race for many Iron Distance Triathletes. In its 25th year, this race continues to be the stepping stone for so many triathletes to get to the next level. Racks are first come, first serve, waves are male/female, and there is a relay division as well.
The 600 yard lake swim is followed by a 2 loop bike course with rolling hills. The 5K run is a beautiful course around the lake which has a few small inclines and downhill the last mile. Aid is available on the run at the town hall section.
