I like training journals for lots of reasons. First, it's my personality and my occupation has trained me to capture data, summarize it, turn it into information, then use that information to make decisions.
So as I prepare for another Thanksgiving Day 10k fun run, I went into my archives to see where I stand in relation to where I stood about a year ago in the running department. Here are some stats for comparison:
Last 10/30/2006
I ran 5 miles in 36:49 (7:22/mile pace) with an
average HR of 156bpm (84% of max) and
highest HR of 169bpm (91% of max). My morning BW was 184.5 lbs.
Last 11/6/2006
I ran 6 miles in 44:01 (7:20/mile pace) with an average HR of 156bpm (84% of max) and highest HR of 169bpm (91% of max). My morning BW was 183.5 lbs.
Today
I ran 6 miles in 44:42 (7:27/mile pace) with an average HR of 160bpm (86% of max) and highest HR of 175bpm (95% of max). My morning BW was 188.5 lbs.
All running efforts were early in the morning, on an empty stomach and on a treadmill at 1% incline (friendlier for my "old" knees).
Conclusion
I'm not quite where I was a year ago but pretty darn close as evidenced by mile pace performance and HR statistics. I'm packing about 5 more lbs. of BW due changes in how I train, and I'm having to work a little harder when I run as a result.
I did have a better summer track season with 200m, 400m and 800m efforts being better than the previous year.
I think I'll be ready on fun-run race day but my per mile performance may be about 10 seconds slower. I can live with that.
But I do like the archival benefit of training logs.
