I vowed that I would run each day this week. I started on Saturday and have run four days in a row so far. Each run took place at the Sports and Fitness Edge gym in Essex Junction, Vermont on their 1/8 mile indoor track.
I was just under 30 minutes on Saturday, just over 30 minutes on Sunday, and just under 30 minutes on both Monday and Tuesday. But more notably, Monday’s run was my first-ever 5K distance run where I didn’t walk at all and I was able to follow that up last night (Tuesday) with another no-walking run. I feel like I’m getting stronger; I used to really start to gasp and ache if I didn’t stop and walk a half lap now and then. Last night, though I was certainly tiring, I could probably have kept on running at the end. When I completed my 25th lap I hadn’t hit the wall.
Interestingly, when I uploaded the data from my Garmin Forerunner 305 to my computer, I noticed that my average heart rate during my runs had dropped each day. Saturday: 160. Sunday: 153. Monday: 152. Tuesday: 147.
I don’t really know what it means that my heart rate is dropping each time — can one really improve in cardiovascular terms over such a short span of time? Still, I’m not complaining.
