Coach has me doing a time trial every now and again. Ive done two in feb, one in march and one in june:
warm up then:
Feb 11th Feb 21st March June
15.10 14.56 15.50 (!?) 14.50 (woo!)
3.48 3.42 3.45 3.47
1.52 1.51 1.51 1.50
On my calculation your current 1500 mts swim time in a wet suit race allowing for, currents , buoy turns , getting a draft or not, swim course can be either short / long or spot on 1500 mts I would be predicting a time of 28 minutes 15 secs.
For a 2 km Half Ironman sea swim in a wet suit my predicted time 36 mins 45 secs .
This Time Trial set is a non stop lactate - threshold test set and not as easy as it looks especially when you havent had a rest day or tapered for it.
My belief is to do a TT set like this " under duress " first time up, then do a taper for it next time.
Keep up the good work and next time we will see times drop by a good 45 secs for 1500 and 60 secs for 2 km
