Interval Cardio

I really went at it hard today. I've increased speeds in both my work and recovery intervals and feel I can go a little faster.

Also, I checked my resting heart rate and what WAS a resting heart rate of 66 back in April is now a resting heart rate of 57.

...I've come a long way from sucking wind just to slow down and brake when ski-iing on the slopes!
