"24th – ride Fort William xc loops"
There's good riding on the fort william XC loops but not really a day's worth. The world cup descents are ace, as are a couple of bits of the advertised 10 under the ben course * but all combined it'd amount to, oh, maybe half of a typical trail-centre red route at most. You'd have to do laps to make it worthwhile IMO. Basically, they're race routes that happen to have brilliant trails in but also a lot of fireroads just to add distance, some obvious join-the-dots trails, and some really pretty horrible climbs. I think it's a wee bit cheeky that they try to pass them off as 2 proper red routes myself, I was very disappointed.
I'd suggest you get a gondola day-pass and do the nevis red "downhill" til that closes then do the WC course, and use fireroad diversions to link Nessie from the 10 Under course into it.
(* the waymarked 10 under the ben course isn't the actual race course, some of which isn't really sustainable… The route we rode yesterday was far, far superior)
