CC82 I have been reading over the various 10k threads the last few days and your one of the names that have been on them all pretty consistently and have 10k times that line up with mine.
Im just starting to get my head around putting in some speed training, although I mostly rotate mile reps and tempos due to the fact I run a fair amount higher mileage for longer distances but have picked up some good ideas for running short intervals too.
Anyway, I mostly just wannted to ask how you got on in your 10k?
I would suggest that for your long runs instead of saying 'Im going to go for x miles' that just finding trails and routes you like and going out for time instead may work better. It feels easier if you enjoy where your running and different routes will take longer to complete depending on the terrain so a 16 one day may take an hour longer than the previous week.
Obviously the long runs are your main training runs for an ultra but if your already used to doing some speed work from the marathon training then I would defiantly keep one session. Its good to keep things mixed up to keep you looking forwards to different runs and they really help to toughen up your legs. It was the one thing I changed between my last two 50 milers and I found my legs were still feeling fresh towards the end even if I wasn't.
Good luck with your training and remember its all learning.
Scott I was just about to suggest that one as well. I did it last year and really enjoyed it and was a fantastic first ultra for me. Lovely route, so much to see and it feels a bit like a scavenger hunt as you tick off each of the items that make up the name.
That would give you 3 months to get comfortable with the terrain and be recovered and ready.
