Fun little data question: After logging a decent number of (slow) running miles over the past couple years in prep for IM's,I spent all fall focusing on the bike and avoiding running. Probably did 50 miles per month in Aug, Sep, Oct and Nov.
With some exceptions most of my runs for the challenge will be 3.5 - 4 miles at about a 9:00 pace. That's my go-to, pay-no-attention-just-run speed at the moment. So the fun question (or at least the question i consider fun): How much will my average heart rate over similar runs decline over the 100 runs? Right now my HR averages about 152 if I do 3 or four miles at a fairly even 9:00ish pace.
After a rest day I went out this evening to run a favorite little 3.6ish mile neighborhood loop. I did it during the first week of the challenge and ran 9:06's with an average HR of 160 - To be fair, my running log notes I ate and felt like crap that day. After that first week I repeated it several times throughout the challenge. The distance varied a tad each time because of where I actually started / stopped running. For the most part I tried to run this route very hard each time so I could use it as a yardstick of my progress:
Run #9: 8:57's with 157 HR
Run #20: 8:29's with 158 HR
Run #27: 7:58's with 160 HR
Run #62: 7:52's with 154 HR (Running log note: Didn't do full effort (as slight HR drop demonstrates)
Tonight: 7:19's with 159 HR
I spent a lot of time doing speed work - intervals, hard tempo runs etc... during the latter half of the challenge. Frankly I did more speed work in those last 50 runs than in the balance of my running life. It appears it really paid off. As you can tell by those times I'm a fairly slow runner; This is the first time it's occurred to me that I don't have to be so slow. If I put some effort into it instead of plodding along at 9:10's all the time I can actually get faster!
Really quite an eye opener.
My only other "test" is the one from my quoted post - On friday I plan to go run this route at the original 9:06ish pace and see what my HR is. I'm guessing it'll be 130ish.
