Reindeer Run data

2008-12-07--Reindeer Run Data
The first lap is slightly longer than the second, and I ran the second stronger than I thought. My watch measured about 300m short, which is normal. The faster I run, the more likely it is to underestimate my distance covered (and therefore speed also). Note how my heart rate was above 90% of maximum for about 37 minutes of the total 39:28. That’s racing!
