I have become a running adict. I am writing a post to describe my addiction, but in the mean time here is a good blog post on problems with pacing.
When I run I am a slave to my Garmin. Not as much as this writer but I check it every couple of hundred yards until my pace stablizes. This morning was tough. I varied in pace about a minute per mile for 2 miles before it stablized. I just can’t run on feel. For example I wanted to run an 8 min/mi pace, but found my pace ranging from 8:30 to 7:30.
