I am always up for a challenge.... But I`m afraid this one I wil have to forego as my winter cycling is restricted to my old Hybrid, outdoors, and it is just to heavy and slow to contemplate any where near a century ride, between 40/50 is about all I could manage at best.
Come the better weather and when the gritters are put to bed for the Spring/Summer/Autumn, that is a different scenario!.
