1. Including lunch, and assuming the killer mile takes a bit of time, 7-8 hours, though I daresay we'd be quicker on the day. The route would also include a cut through a bridleway crossing the River Dane, which I've done on 28mm slicks and have done rougher on my 23mm's, but that people might prefer to walk, which is about 10-15 minutes.
2. Mapmyride says the total elevation is 0.0m, so there goes that estimate! I've done pretty much all the route except the climb before and none of it is particularly taxing hills-wise.
3. Noted on the hill race issue. Like I said, not really thought of dates or owt yet, it's still a fantasy!
Where is this? I know the area pretty well. Plenty of diversions surely?
