You will roughly do 25 100’s on a decreasing send off. Let’s suppose you start the first on 00:00. You need to finish the 100 by 2:00. Every 100 needs to be in by the double zeroes. The next 100 would start at 2:01 and you would have to be in by the 4:00. The third 100 would leave on the 4:02 (one second later than the previous one) and you need to be in by the 6:00. For each additional 100 you have 1 more second of rest and one less second to complete the swim. To make sure everyone gets down to a challenging time lanes will be given different starting times. Most of you will start around the 0:25 so you have 1:35 to complete the first 100 and the second one will start at the 26. Exact starting time will be assigned in the morning.
