Duck, 85% of threshold sounds a bit fast to me to do every long run at. I probably do mine at more like 75-80%.
YP, "close" is relative. I definitely wouldn't say very close, and the slower you are the less close it is. Even for elites, actual marathon pace will be less than lactate threshold. The best (non-scientific) definition of lactate threshold is about the pace you could hold for an hour, so it's more like around 10 mile pace for us; half marathon pace for elites.
My marathon pace (and this is based on heart rate - it would be slower for actual marathon pace) is about 30 seconds or 15 bpm slower than my 10 mile pace.Doing the maths that means my MP is about 6-8% slower than threshold.
I'd be interested to know the difference (both pace and HR) for those who have run both marathons and 10 milers/HMs
CB, I'd thoroughly recommend that session. the second set of reps can be quite tough, but you feel great afterwards and judging by my running logs it has always pushed me on a bit. If you feel really down about running maybe a change of focus would help. Trying a different distance for example or adopting a different training approach.
I did 10 miles last night in the wind and it was a bit tedious. It would be nice just to go for a run without trudging through snow, slipping on ice, being rained on, getting blown around, or bits of me freezing off. Actually, the biggest problem I have when it's colder is that my nose runs continuously.
Mr V, if you can handle the boredom then getting hold of a flotation belt and doing some water running is pretty good - I did it last year when I was having shin problems and I think it's the best cross training you can do for running.
