ATW invite you to the 2nd Merchant Taylors’ Swimming Time Trials.

The event runs from 10.00am. Exact start times are dependant on numbers and entrants will be informed nearer the date.

The event format will be a time trial, non-drafting event with swimmers starting in the water at 30 second intervals. The event will be chip-timed and your time will be taken when you exit the water.

The 750m trial will use our existing swim course that is enjoyed by swimmers daily.

The 1.5km, 3km  and 4.5km trials provide the unique opportunity to use an extended swim course that allows you to swim the west-end of the lake. We require your estimated time in minutes and seconds to enable the seeding of starters.
750m – 1 lap
1.5km  – 1 lap (no time limit)
3km – 2 laps (no time limit)
4.5km – 3 laps (2hr time limit)

Wetsuits will be optional, subject to the following limitation – no wetsuits are allowed if the water temperature is 22 degrees or above. They are mandatory if the water temperature is 14 degrees or below.
