Two tunnel passages, canal paths and a two-lap marathon
The organizer lists August 15, 2027. Its route description begins on the Two Tunnels Greenway and climbs gently toward Devonshire Tunnel. After Lyncombe Vale, the course enters the much longer Combe Down Tunnel, then reaches Tucking Mill viaduct, steps and the reservoir. Practise settling into a comfortable effort after changes in gradient and footing. GPS pace can become unreliable underground, so avoid accelerating simply to correct a watch reading.
Tucking Mill Lane is open to traffic, with runners instructed to stay left and follow marshals. The approach through Monkton Combe and the Dundas and Canal Company car park also passes other visitors. Later sections use the Somerset Coal Canal, Kennet and Avon Canal, Bathampton, Sydney Gardens and the River Avon. Leave passing space and treat crossings as part of the race, rather than assuming an uninterrupted racing line.
The full marathon repeats the circuit. The organizer distinguishes the first-lap turn at Brickfields from the straight-on finish on lap two. Check that junction on the final map and know your lap count; other distances use parts of the same route. A lap-based fueling reminder is more dependable than following the runner ahead at a shared split.
The event information identifies Brickfields Open Space, BA2 1LX, as the event base, with Odd Down Park and Ride and a Two Tunnels bus as an access option. Oldfield Park station is about 800 m away. The detailed information pack is issued four weeks before the event and start lists during race week. Recheck the actual bus and wave times there before choosing an arrival connection.
