I made it around my dualthon last night: 10K run, 20K cycle and 5K run. It took me 2 hours 35 minutes. Now, I'm exhausted.

Whilst I'm feeling quite proud of myself, I'm seriously wondering if I want to do a proper duathlon event. It requires such an extreme amount of training that I'm not sure I actually want to dedicate that much of my life to it. I'll have to give it some thought...
