Can't believe 5 days have passed. Did my third 2:30/2:00 interval run. Which I've gone back to just running twice a week after one week of trying more. (It just really works.) This has been in the tunnel and I've made nice improvement. Actually quite an improvement this time. But also cutting back to beer only 3 or 4 days a week. (Wine on the other days, usually.) With third run, I got almost 2 tunnel lengths ahead. Just going for 100 minutes, which is working just fine. Surely if Roger Bannister could manage a 4 minute mile on 25 miles a week, I should be able to manage pretty well on 20 miles a week.
