For those of you following this thread:
I successfully negotiated the Midhurst 600km Audax on May 24/25 on my trusty Thorn Raven Tour.
This, to me, proves it can do just about anything but race (well, you COULD race but you wouldn't win).
I couldn't find any hotels/motels/B&Bs along the ride at appropriate places so I kept cycling and took longer than normal rests at Tesco cafes & Motorway Services that were en-route. I got back with 45 minutes to spare (but could have easily knocked a couple of hours off if I'd needed to.
I'm really rather pleased with myself and the bike. I know there are quicker bikes out there and there's an element of doing it on the Thorn to prove a point, but it got me round in as much comfort as you can expect after 40 hours (I did have some issues with all contact points but nothing Thorn-specific, just specific to being sat on a bike for 2 days straight).
To put it in perspective, get a map and plot:
Midhurst (Sussex) - 6am Saturday
Chichester
Ropley
Malborough
Cirencester
Winchcombe
Newent
Hay on Wye
Magor
Leigh Deleamere
Sutton Scotney
Petersfield
Midhurst 377 miles later @ 9:45pm Sunday
It was quite an adventure and quite remote at 2am around the Brecon Beacon valleys. It's taken under 2 years of Audaxing to get to this point, starting with 100km Audaxes in 2007.
I haven't sat on the bike since I got off it in Midhurst (377 miles in under 2 days is enough to put you off for a while) but I need to get myself busy for a 400km in 3 weeks. This will get me my "Super Randonneur" title (200km, 300km, 400km & 600km in same year). At which point I intend to use the RT for shorter pleasure rides until 2009, at which point I may do an SR series again. I need to keep in shape until 2011 so I can stand a chance of doing PBP. I am undecided what bike to use for that although the RT would definitely get me around.
Summary, don't think you can't cycle a long way on a Thorn RT.
Here's me (painfully close to my house) with 330 miles done and 47 left to go. Everything on the rack and in the bag are soaking wet (including the shoes I am wearing). I am wearing any dry clothing I have left after a horrendous morning, starting with crossing the Severn Bridge at Chepstow around 7am just after it reopened (high winds and torrential rain).
Like I say, Audax can be a mini-adventure. I highly recommend it.
