Stitch - how is your training going? Hope you haven't given up on the idea already!

25 miles is that not far, tbh, just go out on the road. The rule of thumb for running is that if you can comfortably do 13 miles you can probably do a Marathon if mentally prepared. So I would aim for at least two 10 mile rides a week for a while, then try to get that built up to a few 15-20 rides the 2-3 weeks before the big day. If you are really starting from zero, then do 5 mile rides 4 times a week for the first month or so.

That's what I would do, not that I'm a fitness expert or anything.

if your charity cycle ride is hilly make sure you practise on hills, cycling on the flat is quite different.
