Ikle, you missed TOTP?
Once you start doing the long runs, the weight usually comes off so not surprising. The slower speed is or should be more in your fat burning area. All helps improve speed, so running will get easier for you.
Martin, didn't quite follow the PB bit. you mean your recent marathon? Good luck tomorrow.
Susan, 5 miles for this week, you did XC & a half marathon at weekend, so last 7 days is 25-26 miles. More than me
A lovely (tough) 8ish miles last night, a threshold rather than a steady tempo run.
Warm up, 3 miles MP, 2 miles at roughly 15k pace, 1 mile MP, cool down.
W/U 8:25, 7:45, (5 min break at club), 7:11, 7:15, 7:19 (some hills), 6:30, 6:35, 7:14, C/D 5 mins jogged.
Felt tough but not the last mile @ MP weirdly. Good session to try.
