The excitement is mounting — and so are the nerves.
Tomorrow I am taking part in London Nightrider, which involves cycling 100km (62miles) around the main landmarks of London, starting at midnight and finishing in the early hours of Sunday morning.
A map of the route can be found here.
My trusty Trek FX has been freshly serviced — and just as well, because the mechanic told me the back axle was broken, oops — and I've got my little bag packed with snacks, first aid items and my camera.
I think I'm physically prepared for the event — I've been cycling fairly regularly — up to four commutes per week, plus a handful of longer 20+ mile trips to Richmond Park — since April.
Plus, thanks to the magic that is my FitBitFlex, I've been walking a minimum of 10,000 steps (or 5 miles) every single day since January 6 — rain, hail or shine — and have lost 8kg in the process. In other words, I'm a drastically slimmed down version of the cyclist who tackled last year's London Mitie Revolution and feel much much fitter than I did then.
While Nightrider is not quite as massive as that challenge (290km/180 miles over two days), I think it's going to be a struggle to stay awake all night (I do love my bed), but perhaps the adrenalin, excitement and novelty of the event will help.
Once again I'm raising money for Arthritis Research UK (an organisation close to my heart as I was diagnosed with psoriatic arthritis in 2008), so, if you're feeling generous, you can donate a pound or two via my Virgin Money Fund-raising page.
In the meantime, wish me luck — and do think of me cycling the capital's streets while you are tucked up in bed tomorrow night. I think I might need to put espresso in my water bottle to stay awake!
