Edinburgh sprint triathlon

I have never been a great trainer during the cold winter months but idea of a new years day Edinburgh sprint triathlon at commonwealth pool & round Arthur's seat was too tempting. So yesterday I done race route, the cycle had 3 very steep hill climbs which played negatively on my mind especially the 3rd one, yet on reflection physically I had no big issues, my legs felt strong & breathing steady. The run was mostly a walk but again feel I could have done more, breathing was OK & again felt strong. Overall considering the conditions I encountered are exactly ones that my DCM struggled to previously deal with I think physically I am on right track but this is so more about mind set & belief. I wake following morning with no aches or pains but just being careful by lying in bed before work. One worry was after all done the stairs at changing rooms at commonwealth pool caused me to feel physically tired,weak & dizzy, think it may be down to not having fluid during training but again just a time reminder of the need to be very careful.
