Sorry to hear of your accident old boy. You are in good company, three of my friends have had big uns in the last month- one is still in hospital and has lost the use of his right arm due to the severing of the nerves in his shoulder.
I like the look of the velo 24hr. I've done a few 24hr races over here as part of a team. Didn't take it serious at all, just the craic, beer, heckling etc. we should put a Club Arnage Team together!
Logistics are looking better now with the kind offers of getting the bike home. Getting back on Sunday is critical to getting a pass out. A quick look at the timetables shows I can be home in time for last orders at the Tap and Spile.
I need to look more closely at the outbound side of things now. I'll be using my Fargo which although it runs 29" wheels and drop bars, it's still a mountain bike. 100 miles a day is fine on a whippet like carbon road bike, but harder when running a 3" wide tyre up front. I'll also be unsupported, therefore carrying all my kit.

It's 122 miles from the station in Paris to the circuit. If I can clear Paris on Thursday evening and chip 30+ miles off before finding somewhere to sleep then I think the rest should be ok. I'll whack 45 psi in the tyres and get down in the drops. If its reasonably flat I should do it in 11-12 hours. Adds few hours for food, rest and drink and my aim to be at the track by midnight Friday should be achievable.
I think I have my kit list sorted. I will travel light- Alpkit Bivy bag, 3 season sleeping bag and Alpkit sleeping mat, spare clothes, a few tools, a spare tube and pump plus 3 x 150ml bottles. No tent, i will make do with a ultra lite tarp if the weather turns. I will eat as I find, rather than carry food. I will also want to take camera gear plus a GoPro HD camera to do a wee video diary of my adventure. Navigation will be via IPhone with Memory Map loaded up. Slight concern over battery life there, which I need to look into.
If you can think of anything else I might need then please shout. Any suggestions welcome.
