Starting the Program

So, yesterday was the first day of my half-iron distance training program.  I ran about five miles of intervals with Mel and my running group at the YMCA.  For those who don't know, intervals are periods of fast running followed by periods of slow running.

This is what Wikipedia says about interval training:

Interval training is a favorite of coaches because of its effectiveness in cardiovascular build-up and also its ability to make more well-rounded runners / riders. However, it is also applicable to exercisers as it helps improve exercisers’ aerobic capacity to exercise longer at varying intensities (Mayo Clinic, 2009).

This is a basic  interval training chart

Interval training can be an effective means of enhancing an athlete's lactate threshold. Lactate threshold has been shown to be a significant factor determining performance for long distance running events.

This method of training may be more effective at inducing fat loss than simply training at a moderate intensity level for the same duration. This is due to the metabolism boosting effects of high intensity intervals.

This is where I swim, minus the kids.

The running went a lot better than I thought it was going to.  I felt pretty good after taking so many weeks off and eating whatever I wanted.  However, I did feel some discomfort in my left ankle, so, I'll have to keep an eye on that.

I also got back in the pool today.  The wrist is not ready for swimming; it hurt to pull backward and I couldn't really put any power into my left arm.  I decided to do some kicking drills and also use my fins.  With the fins, I can still use my left arm to work my shoulder and back without needing to depend on power from my left arm to propel myself forward.  Hopefully the wrist will heal quickly because swimming is my favorite part of training. 

Tomorrow is a bike day.  Sweet.
