Can anyone who has run it before or knows the course comment on the enormity and scariness of the hills?! The website shows a rather lovely view looking *down* on the cathedral and I'd like to be prepared for how hard it might be to get to see that particular view! How much time might be lost compared to a flatter 10m?
A second vote for the Maidenhead HM from me. It's all on road, as I remember, but a great course (pretty much flat) and certainly a brilliant atmosphere. It's 2 not-quite identical laps and makes the most of the town centre, so you tend to get lots of supporters congregating.
Try to persuade your colleagues to run with you ...then there's no-one left to mind you all "glowing" somewhat for the rest of the afternoon! I agree with the sentiment that "where there's a will there's a way". In this weather especially it's sometimes a real treat to be able to get out and run in the daylight. It gives you a smug feeling that, by the time you get home, you've done your exercise for the day and don't have to get dressed up to go out in the cold and dark. If you can get your workmates running as well it'll do wonders for team spirit and motivation!
