After the success of our London-Brighton-London earlier this summer, my Channel 4 colleague Peter Heneghan and I have decided to tackle something a little bit bigger...
So, we've decided to tackle some - I'm hoping a dozen - of the Tour de France's toughest mountain climbs in a week-long tour.
Peter's brother (who's a pretty serious cyclist) and my brother (who isn't) are keen to join us too.
The route is currently under discussion, but we hope to do a couple of days in the Pyrenees and a couple in the Alps, plus one en route. Here are some of the mountains on the shortlist, many of them evocative for anyone who's ever followed the tour:
Alpe d'Huez (1860m), Aubisque (1709m), Col d'Agnel (2774m), Croix de Fer (2067m), Galibier (2645m), Glandon (1924m), Hautacam (1560m), Izoard (2360m), Solor (1474m), Telegraphe (1566m), Tourmalet (2115m), Mont Ventoux (1909m)...
Most of those mountains are counted as Hors catégorie - meaning 'beyond categorisation' - i.e. very high and very steep!
At the moment, it's still at the planning stage - and subject to consent from Mrs Robinson - but if it goes ahead, it's going to mean some serious training...!
