Hi BillyBudd - April is a long time away yet and I would say its too early to set a target time, just do the training and then see how that goes and then set yourself a range of target times
1) In the bag, could do this time with my eyes closed
2) Realistic, I'd be happy with this
3) Dream time - this shouldn't be 2:30 or something, but say if everything goes really well on the day, so perhaps double your half time (from a half you do in Spring or Gosport) + 5 - 10 minutes
Don't skimp the long runs, I've done 2 marathons before and the pain you feel at 20 miles is the toughest thing - get through that and you are done.
I also did GSR on Sunday (72:25) and am pondering on Gosport, currently trying to build up my long runs by 1 mile a week, so GSR at 10m last week, this week, 11m, next week 12m, Gosport half fits quite nicely into that sequence. When I get to 20 + (around Christmas) I'm going to try and keep that going into the Spring as that is the point which finished me in Vienna and Barcelona so I need more long runs I think
- Some triathlons have somewhere you can change (ie a tent) between swim and cycle, so you can put on cycling shorts and equally from cycle-run to put on running shorts. I don't have a tri suit and my previous Olympic Distance tri's I've worn running shorts and vest under my wet suit and put up with a pain in the ar5e on the cycle, but obviously cycling a bit further this time. Is there a tent (or equally can I get changed next to my bike, with a towel round my waist?
- I wear glasses. Obviously I will want these on the bike and run, but not on the swim (my vision is good enough to get from swim to bike area). Normally I would leave my glasses in my cycle helmet just before I walk down to the water for the start, but it looks like you can't have access to your bike in the morning - any advice much appreciated
