I'm game for this, especially given the elite company that we may be keeping.
Romsey would be a good starting point but you'd need to change trains at Southampton if coming from London I think. You could start from from Soton Central but it's not that great a ride out to the NF from there. If I can get a pass, I'm happy to escort a delegation from Winchester Station to a Romsey start. Quick and flat on the A3090 or lumpy and stunning through Farley Mount and along the Test.
Are you taking route suggestions? I think Godshill, Sandy Balls (knock yerself out with that one, 'teef), Bolderwood and Rhinefield have to feature.
