Thanks again guys, I'm absolutely lapping up this advice, and am going to spend a good bit of time route-planning those details. Very decent and generous of you to help me out by passing on these pearls of wisdom.
Pace-wise, after some early blow-ups, I pride myself these days on being super even-paced in a marathon -- but won't have a clue how to tackle the pace in this. Obviously any race feels beguilingly easy from the off, but I guess there's also the factor of the climbing muscles getting a bit of a rest on the downhills and vice versa, though they overlap of course. Will just have to run to feel I guess, and not forget that it's a serious endurance event...
We came down through the quarry on a family walk last year. Sounds positively suicidal racing down it, but hey, I'm in!
