Here's what training for an Ironman involves (for a mere mortal like me). In a week I'm on the bike three times, in the pool twice and out running three times. This week just gone I rode for about 6.5hrs, ran for 2.5hrs and swam for 2.5 hours. That's 11.5 hours of training and this is an easier week. Getting up early on Tuesday to run and Wednesday to ride is probably the hardest bit, and not just for me. I think I'll setup a stretcher and sleeping bag in the garage!
Apart from that time the other things to contend with are the mountains of clothing that needs a wash and the fact that I am constantly hungry!
The rest of the family are saints in my opinion. Especially when they all know that there is still 4 months to go!
