Hi Graham. I'm involved with the St James' Way, as a volunteer with the CSJ, helping to maintain the route. It is a fabulous UK pilgrimage, but it does have its challenges on several sections. The route is mainly along footpaths and whilst many of the stages would be navigable with a hand trike, there are several sections that are close to impassable other than in single file, and with care.
There are possible road detours along some of the sections, such as the approach to Silchester which gets very boggy in the fields and woods, but other sections such as Eastleigh towards Southampton alongside Itchen Valley Country Park, for example, do not have road options, other than busy main roads some way away.
The first day out of Reading is doable as it follows the River Kennet, as are sections around Basingstoke, New Alresford, Winchester and Southampton. Out of curiosity, I checked out Ben's profile... he really is a remarkable man, and if anyone can rise to this challenge, I'm sure he can. However, putting my pragmatic hat on, I'd recommend you take a look at the route first of all, maybe you can do sections of it with Ben, although I guess not ideal for your challenge.
I've not walked the route since last Autumn when I did some route maintainence near Eastleigh, and it was very overgrown (see photo below... after I cut it back!) However, there is not as much growth in the spring. I plan to check out the route over the next few weeks and would be happy to feed back to you.
Wishing you every success,
Peter
