Training Hacks for Ironman: Traditional Vs. Crossfit

I didn’t do this on purpose for any means, but over the last two years I have completed two Ironman 70.3 distances (Boulder both times) with radically different training programs. Today I looked at my times and think there are some pretty interesting conclusions.

2009: I raced the distance for the first time with pretty beginner, but not poor, gear.  My training was a six day a week, at least an hour a day, schedule.  About 14 hours a week if you included the longer bike ride on Saturday.  Three ‘bricks’ or multi sport days (a run then a bike).  It took a great deal of effort and I was very proud of my first 70.3 distance:

2009
57:23 swim
2:44:14 bike
2:30:18 run
6:18.15 finish time

Recovery from the race took a full week of very sore knees and legs.

2010: There were so many weird things about this year, but I never really got my traditional training into gear.  I was training at Crossfit Roots in Boulder and loved about everything they had.  A intense challenge with a focus on a fun community.  I didn’t have to worry about solo runs or workouts, they had quality coaches to keep you in check and push you when you needed it.  When I raced in August, it was my longest swim, bike and run of the year.  I was proud of my effort as well (especially for my three hours of training a week):

2010
45:14 swim
2:44 bike
2:50 run
6:25:06 finish time

After the race I drove myself to town, had drinks and dinner with friends and went for a nice relaxed run the next day with very little soreness and a massive racing suit tan.

What does the data tell us?  What did other things contribute to the races (such as, in 2010 it was much hotter and as you can see I bonked on the run).  I finished within seven minutes with completely different training styles.  In 2010 I had a nicer bike but also a foot injury.  Offsets.  I wasn’t a rookie and knew what to expect for my swim (the time shows this) and was more relaxed.

If I were to do it again, I would do Crossfit with some longer bike rides to get my cardio up.  Mix in some 400 meter running sprints and a once a week mile swim (400 meter sprints as well).

The final word: you don’t have to train traditionally for longer endurance events.  My longest workout going into the 2010 race was 38 minutes.

That is crazy talk. It worked well though.
