In reply to mountainbagger:
Good to hear it paid off! Well done.
Coincidentally I ran my first HM yesterday and just dipped under 1:30. It was a trail race and really muddy, I stupidly ran it in lightweight road shoes so didnt feel very sure footed.
Looking back at that thread I see I have signally failed up follow my own advice. Since Xmas my weekly mileage topped out at 35m and averaged more like 25. Two weeks ago I did a hard interval session and a 13miler the next day. Then the following day a short easy run accompanied by foot pain. Last Wednesday I did an even harder speed session (pyramid) which left me tired for the race I think (and still with a sore foot).
Conclusion: build up the mileage slowly and don't think you're indestructible because you'll surely get injured! I've learnt a lot from racing new distances though (10m in Dec, then a half). I think you need the extra training distance much more so than with 10k; certainly my half time is some way off my predicted time based on 10k.
