Now there isn't any scientific testing behind the bombastic-ness of the title for this post, and frankly I wouldn't have noticed had it not been for Strava's "Matched Runs" function.
After finishing an hour of calm running yesterday I did my normal routine of stretching and uploading the activity to Garmin and Strava. After the run was uploaded I went online to check and change the name if the activity.
The matched runs function is probably the best reason to use Strava as you'll get comparisons that you have never even thought about doing, not only for race pace, but also as important the heart rate.
Yesterday's run had indeed a matched run, and the differences in these two runs really caught my eye. The pace of these runs have close to no significance as they were very easy runs where I talked and wasn't focused on running fast.
What really caught my eye though, was the significant difference in average heart rate, especially when the fastest run had a much lower heart rate level. This might be a one time thing, but after a lot of really good weeks of training my hope is that, this now is the norm. If I keep on training like now, the chance of progressing should be definite, and I1l keep checking on Strava as I get closer to Alcatraz!
