Blisters / Cake, completely agree about Buxton sprint, the cycle leg is fantastic. It was my first tri so holds fond memories and now has a fixed place on my race calender.
The DIY half in Macc souns great and by all accounts was well recieved last year and good numbers listed for this year. I believe there is a hread somewhere by Silent Assassin and his better half.
I'm entered in the Outlaw for 2013 so will be doing a half around the time it is recommended by the Don Fink plan, hopefully the Macc event will fit the bill.
