Athletes will be lined up along the wall according to estimated swim times. If your estimated swim time has changed, please call the Longmont Recreation Center at 303-774-4800 BEFORE 12pm on Wednesday, August 19 to update.
The fastest swimmer will enter the water first. A representative from the timing company will enter race numbers into their timing system and will give instructions when to start. After the first swimmer has completed one length of the pool, the next swimmer will be told to start.
How to do the snake swim: Dunk under each lane line to change lanes during the snake swim. When finished, exit the pool via the ladder or climb out over the edge of the pool. Exit to the transition area from the pool door. This is where the first timing split will be collected.
