Well done at Swansea pip and glad things are going well again. Like the idea of a tag triathlon and would also want to do the running leg. Not sure when Cardiff is for you but if a while away just train for the 5k, maybe do 600m reps with 200m recovery x 5
Why I'm enjoying running again since last posted, injury touch wood has been good and have managed a 5k and 10k PB in that time. 20.20 and 42.32
Travelling from Kilmarnock to Edinburgh will be as long as travelling from your own house, don't see much benefit in that. You could consider staying somewhere like falkirk, linlithgow or Stirling with direct trains into Edinburgh in around 25 mins and digs should be a lot cheaper.
Yeah I was a bit nervous about running again but that's three weeks now and I'm back into the way of it. Started with a slow 2 miles and did 8 miles at 8.30 pace yesterday so getting there. Still a bit to go to get back where I was and the biggest issue with me was letting my fitness slip.
