Run: Speedwork (and how to determine max heart rate)

Course: East 6th Street Track
Distance: 4.1875 miles
Realization: "Training = Improvement"

Speedwork was not so bad today. I actually felt stronger, and I could definitely maintain a good pace for an entire half-mile.

I also discovered that my maximum heart rate is probably a little higher than I previously believed. My heart rate monitor indicates that I hit my maximum heart rate at some point during my workout, but I definitely don't feel like I did. I put my max heart rate at 190 using the standard 220-AGE=MAX HEART RATE formula (or the newer and probably more accurate 205-(AGE*0.5)=MAX HEART RATE), but there are always going to be variations among people who are the same age given differences in genetics and physiology. So after today, I'm going to cautiously bump my max heart rate up to 192, putting the age of my heart at about 28 or 26 depending on which formula you use. I thank my farmer ancestors for their strong hearts and clean living. Who knows, maybe they could have been elite athletes if they had been given a different lot in life.

The Workout:
3 x 200m + 100m recovery
800m + 400m recovery
600m + 200m recovery
400m + 200m recovery
600m + 200m recovery
800m + 400m recovery
3 x 300m + 100m recovery

At pace: 4100m (2.0625 miles)
With warm-up and recovery: 6700m (4.1875 miles)
