So I ended up running fairly even splits and finished in 1:11, so very much closer to my 10k pace but in fairness, I think I'm on for a massive PB in my next 10k.
The plan was to run it at 7:15 miles but when I got out there I felt really good so just went on feel. In hindsight Reg was spot on, everything went out of the window as I found form I didn't know I had.
I had a strong wind behind me from mile 8 so really went for it in attempt to get under 1:10. Big mistake - last mile was hell and felt as though I was going backwards.
Hmm..I'm doing a 10 mile run. My question to myself is "do I run it at closer to my 10k pace, or closer to my HM pace.
If I run at a pace that is faster than 7:15 miles on average, but with a slower first half, then I would describe that as being closer to my 10k pace, but with a negative split. Makes perfect sense to me, perhaps I just live on a different planet to everyone else
Anyway, to quibble over little technicalities like this is a waste of valuable energy. Cal & TR have given good advice, and I've decided how I'm going to approach it now. Thanks for the useful responses guys.
Lol, I'm not overthinking it, in fact I'd say I've under-thought it, hence wondering if anyone can offer advice.
"try a pace in the middle and see how you feel along the way" is exactly what I'm suggesting: negative splitting means, broadly, running a slower first half. So if I go out at, say, 7:15 miles and increase towards 7:00 miles in the second half of the race then my time will be closer to my 10k pace than my HM pace.
Just wanted to know whether this too fast and if instead I should aim for something closer to HM pace.
