I post this on behalf of toodlers everywhere (you know who you are).
I embarked on my short-lived racing career Sunday in a duathalon at Pioneer's Park. My wife is a runner and thought it would be cool to enter as a team.
It was great fun, in a sort of masochistic way. The race was a 2-mile run/12-mile bike/2-mile run. The bike portion was three laps around Pioneer's Park. I've not pushed myself like that on the bike before -- going hard for 30-40 minutes. The best parts were 1) teaming up with my wife and having our 4-year-old son be the "coach" -- hopefully, growing up seeing his parents be physically active will rub off on him. And 2) hanging out with all the friendly and supportive people who were there. There were several teamFIRE people out there -- both racing and just showing support.
It was a great time and I'm glad my wife took the initiative to enter us as a team. I'd like to do it again next year -- if my teammate will pick up the slack for me again, of course.
