After looking at Mr. Arrogant's workout schedule, I was impressed. He ran pretty much every day. Sometimes, twice a day. He logged more mileage in three days (sometimes 2) then I did in a week. I used this information and channeled this anger into my interval workout last night during Matthew's soccer practice. The workout called for two 4 minute intervals at threshold/5K pace, then three 4 minute intervals at half marathon pace. I nailed every interval and was actually surprised at how easy the half marathon pace felt after hitting the 5K paces :-)
This workout marks my transition from heart rate based training to pace based training during the run. A lot of triathletes are already doing this on the bike by training with power. I suspect that heart rate training has been holding me back a bit, and I aim to find out if this is true, or not.
