I'm so glad I saved this as a Word document. When I first heard about last year's Loch Ness Marathon, I went out and drove the course (sad, I know) and posted this on the "old" forum.
""Thankfully, the course starts on the Inverness side of the nasty hill I remembered near Whitebridge, so it's not quite as bad as it may have been, but it will still not be a PB course!
The first 4 miles are downhill, which is just as well, as there are two really nasty hills at 4.5miles and 5.5miles. Both are followed by pretty steep downhills which will give a bit of recovery, but might be hard on the knees. 7,8 and 9 are flat to downhill, and then it's pretty flat right through to 17. The only hard bit about 10-17 is the small undulations of maybe 20 feet up/20 feet down (the kind that make kids carsick), which you probably wouldn't notice on a 4 mile training run, but will feel like mountains after the earlier hills.
The killer in the course is the 3 mile uphill drag at miles 18,19 and 20. 21 is downhill, then there's a short sharp rise at 21.5, followed by some larger undulations. From about 23.5 onwards it is gently downhill to flat right the way to the finish.
The scenery is to die for (preferably not literally), and will take your mind off a lot of the pain. You are close enough to the loch for over 10 miles to do some Nessie spotting, and there are a couple of landmarks to look out for - Boleskine House at 7 miles, which was the home of Alister Crowley and is said to be the most haunted house in the country, and Urquhart Castle on the other bank of the loch at about 14 miles, which is the one on all the postcards with the fake Nessie printed on it. You also run past (well,below actually) Inverness Castle in the last mile.
I'm seriously considering it, despite having said after London 2000 that I couldn't imagine running 26.2 without the aid of the cheering crowds........""
Having run it, this pretty much holds true, although I was about half a mile out on my calculations.
