Hi all, thanks for the advice. I took onbaord and the race went very well. Legs felt strong throughout and although tired, were not sore at the end. In fact my legs were in a lot of pain over the last 4 miles of the Edinburgh marathon, which I presume was the effect of the tarmac compared to offroading!!
To summarise the training for those interested. I had 5 weeks between races. I rested for 9 days after the Edinburgh Marathon (only swimming to keep up some fitness). I then gradually came back with the 30 to 40 minute runs over the next few weeks, building in a 1 1/2 hour run at the end of week 3 and a 2 1/2 hour run at the end of week 4 (the week before the race).
I agree with Hillheader, its an amazing run. Thinking about where you put your feet keeps your mind busy and the views are amazing. Yeah Aviemore are generally unaware a race is taking place on the day!!! : )
Oh time was 4:44 which put me in the middle of the pack result wise. They had a record entry this year. 153 compared to an average of 80 in previous years!!...so please don't tell too many other people ; )
