That's really good Henry, impressive stuff. I'm doing the Leeds half marathon in about a month (which I've heard is also quite hilly) but I've got more modest goals, just hoping to crack 2 hours!

Which marathon are you doing? The idea of a summer marathon would scare me a little bit. I would end up fixating on the possibility of waking up that morning and it being blazing hot outside, which I can only imagine would make the whole experience very unpleasant.

I'm still on for the York one in October myself. I'm feeling quite good about it so far, I definitely feel like the training is well on track. I've been managing to pick up the pace a little bit over more extended distances lately too. My last two runs I broke my 10 mile PB on both occasions, and still felt like I had something in the tank at the end too.
