m..eface, The lake laps are 950m, I managed 3 laps in 1.18 last Saturday on my second ow swim, not incredible but I'm fairly confident based on that that I can manage 3.8k inside the 2hr cut off.
However. The 10k swim has a 3.5hr cut off, that's about 6mins per k faster than I swim now. I'm thinking maybe consolidate the lake swims and aim to be doing 5-6 laps by the end of July and I will be fine for my long course in Aug, but I need to be working to get faster for the 10k.
That leaves 2 pool swims per week so rather than just swim up and down for 60-90mins I'd like to do something structured to get faster. 10k cut off pace is around 1.20 for 3.8k. So starting on June 10th-what sets and how do I progress them between then and the end of Aug?
Thanks
