I did my first half Ironman last week

It's a 1.2 mile (1.9 km) swim, a 56 mile (90 km) bike ride, and a 13.1 mile (21.1 km) run.

I'd never done a triathlon before so a rude awakening in terms of training for three things at once. I finished around 5 hours 30 which I was reasonably happy with. I'm never going to do another one but nice thing to check off.

It's a bloody long way... I think training for a full ironman would be a full time job

Congratulations.

I hope to run a marathon one day.

I did one a few years ago, it was an amazing thing to work towards and smash out.
