Nope - there's something about this RW site that brings out my inner luddite 
I get that feeling sometimes, also in the right leg, as well as those bizzarre felings of your leg momentarily giving way!
8.4M at average 6:25 pace for me at lunch, with 1M warm up, then 6M tempo. I was intending 6 miles at HMP, but a serious headwind for part of mile 4 and most of mile 5 wore me out, so did the 6th at MP instead! Still, it meant I'd done a 38:10 10k at lunchtime - a couple of years ago I'd have been pleased with that as a race time!Splits for tempo section were: 6:02, 5:59, 6:01, 6:08, 6:15, 6:30.
After much wrangling with Stoke Mandeville over the past 6 months about the cost of using their track, they've offered an unlimited use deal for £22 per month. Seems reasonable, but still not sure given I'd only be using it once a week for 40 weeks of the year, so still works out at close to £7 per session....
Oh, it's going to rain, shall we close the roof - no let's wait until the pitch is waterlogged and the roof can't be closed (because its raining!) Genius!
