I am doing my first TRI this September, and I have a little bit different case than most. In october i will be having ankle surgery... if i run more than 3x/week my joint will swell and I will not be able to walk for 2-3 days (let alone train)... i have been spending most of my time in the pool and on the bike (which i am not very fast on either 1:50/100m pool and 21mph bike avg over 15m TT). Today is my first bike/run workout, and have been running 1-2x week shorter distances.

I have done 1/2 marathons and obviously just trained with running for those, how far do you guys/gals feel your general fitness can take you in your TRI training for race day?
