Martin submitted the winning design for London’s first dedicated cycle route in 1977.

Now, 43 years on, the ground survey and GPS mapping of a system of recreational rides around the capital’s urban periphery is complete. The route comprises 12 arcs, 12 spokes, and 12 spin-offs. In total, it covers more than 750 miles of off-road and quiet cycling through varied landscapes – often beautiful, always interesting.

In a reference to the London orbital motorway, the M25, the working title for this cycle network was the C25. It is now (July 2020) in the process of acquiring a new title, logo, brand image and a dedicated website from which the routes will be fully accessible, excursions planned. While this is in development please enjoy this blog library of recent adventures, or from the archive of photos taken on reconnoitre. They are laid out chronologically below.

Please contact Martin for further information, or ask for access to the website as it is being built by Anthony at Fonant.

Beyond Spinoff 9: Didcot – Maidenhead via Henley

This was a ride concocted from the need to deliver items to near Didcot power station, and to explore a ride back via Wallingford and Henley to the end of Spinoff 9 at Crazies Hill. I was also enticed out by a bright frosty day with a brisk westerly to blow me home. Having taken the 9.20 Paddington train I was ready to set off back by 10.30, but it started badly; Continue reading

Arc 2B revisited – investment and improvements

Project C25 has taken a back seat in 2019, though I have been checking on the condition of the routes, finding to my relief minor improvements in many places, and little evidence of degradation and thankfully no disrupted or closed paths. For instance, yesterday I learned that downstream of the Thames Barrier “the missing link” had been installed. Continue reading

C25 Arc 10: a lucky escape – and a plea to take care.

The C25’s purpose is to entice the rider out beyond the metropolis into pastures new. While designing the system I was aware of the importance of noting potential hazards along the way. Last week, out of the blue, I was thrown by a potholed rut between the surface of the approach lane and the main A40 carriageway in Beaconsfield, and left unconscious by the roadside for 20 minutes.
