Last swim session and it looks like something may have clicked with my swimming. I've managed to slow my pace down to something i can now sustain for far greater distances. My last set of the evening was 500m FC, I completed that and didn't feel i had to stop, breathing felt good, and the mile before new year seems more achievable.
Coach after the session gave me a couple of sets to try and work on first was 3-500m wu, 100m, 200m, 400m, 800m with a small rest between each set. Next session should work the opposite way, 3-500m wu, then 800m, 400m, 200m, 100m. His other sugestion was 3-500m wu, then 4x400m with 2 min rests between sets, each time i do this i should try to reduct the rest time until i can do the mile.
Ended up with a cold that was threatning most of last week setting in sunday afternoon, normally i just keep going with work and i really struggle to get rid of colds. This time i took a couple of days off, ended up sleeping for 17-18 hours monday, and woke up feeling loads better, did the same tuesday, and today I'm back in work and feeling better than i was before the cold set in. Training is a little behind, but if I'm still feeling good tonight I'll go along for another hours swim session.
