Solo (sort of) intervals -- Tue. November 25

After a long day at work, felt I just had to get out on a damp and chill (but still, fortunately) evening -- no moon, but cloudlit. Went out in shorts but hat gloves and jacket, and road shoes: aimed to take first mile gently, then push hard for a few minutes, and then alternate as best I could thereafter. Went on a route I've used in evening runs before: down GeoHannum, all the way to Stebbin, then left to 202, up to Boardman, and along to go back on GeoHannum -- I knew that was about 7-8 miles. As it happened, I did a solid first mile, easy but good pace; then pushed hard for about half a mile (checked GPS), then slowed up for the rest of that mile and one more, then pushed hard again for just over half a mile, and then slacked off again, at which point my leg was going numb. So at five miles I had to stop for a minute or so, then did another couple of miles at a regular training pace, at which point numbness threatened again. Stopped clock and reset, then jogged another 0.78 of a mile home. Here's the first bit:

Time: 49:35
Distance: 7.19
Pace/speed: 6:54/8.7 mph

Then add 0.78 miles @ 8:12 pace

Comment: apart from the numb leg problem, this was an interesting run. Rib was a bit sore, maybe because the pace was harder than Sunday. My "intervals" gave faster miles for 2 and 4, thus: 7:09, 6:39, 6:51, 6:30, 6:57; then 7:04 and 6:56. Useful experience, and I'll have to keep working on it. I noticed that half a mile feels about right for max pace, but in the second "interval" I definitely felt much more tired. I need to try and work a run with three intervals. . .
