The starting point is the Deerleap car park (on Deerleep Lane off the A35) (50.88485, -1.499615 in Google Maps).
Lunch is at the Alice Lisle pub (13:15 for the moderate group, 13:45 for the other lot)
The shorter route (101.54 km with 630 m ascents) (63,1 miles, 2,067 ft) – planning to leave the car park at 09:30
The longer route (161.62 km with 1,111 m ascents) (100.43 miles, 3,645 ft) – planning to leave the car park at 09:15
An intermediate route suggestion (114.2 km with 834 m ascents) (71 miles, 2,736 ft)
For the shorter route, I have included a suggested stop at the Coffee & Drift near the harbour in Lymington.
The intermediate route has a coffee stop at mile 23.
Hopefully, the weather will be kind.
