Full Chiltern Wonderland 50 Route Breakdown
A single 50-mile loop out of Goring-on-Thames and around the Chiltern Hills, taking in sections of the Thames Path and the Chiltern Way. It is the gentlest-feeling of Centurion's 50s and the prettiest: beech woodland, chalk lanes, and a string of villages that will look familiar to anyone who watches British television, since this corner of the Chilterns is a standing location for it. The loop returns to the same village hall it started from.

Training Strategy for Chiltern Wonderland 50
20-24 weeks is the realistic window for a first 50-mile ultra, assuming you already have a marathon's worth of base behind you. The block that matters is back-to-back long weekends — a long run on Saturday followed by a second, slower one on Sunday — which builds time on feet and teaches you to run on tired legs without the recovery cost of one enormous day. Practise your race-day nutrition on every one of them; at this distance the stomach fails before the legs do.
This is a largely flat course, so most of your long runs can mirror that — flat and steady, building time on feet rather than hill strength.
Drop volume hard across the final three to four weeks — further out and steeper than a marathon taper, because a 30-mile training day costs weeks of recovery, not days. Keep some easy running and a little terrain-specific work in, but the goal is to reach Goring Village Hall, High Street, Goring-on-Thames, Oxfordshire RG8 9AG with fresh feet and a rested gut rather than one more long run in the bank.
Lock in your target pace using the interactive splits calculator below — no official pacers are confirmed for this event, so a pace band on your watch is the more reliable option.
Test your race-day fuel and hydration plan on your long training runs, not for the first time on race day — check the Race Day Checklist below for what's actually on this course.
50-Mile Ultra Nutrition & Fueling Plan
A modest carbohydrate increase across the two or three days before, with nothing new introduced.
A carbohydrate breakfast two to three hours before the 08:30 start, of something already tested on a long run.
Five aid stations across 50 miles means roughly ten miles between them — a genuine gap. Carry more than you would at a race with seven or more stops, and use each one properly rather than passing through.
Hot food is served at the finish. Eat it there.

Goring-on-Thames / Streatley
Start, finish and everything else in walking distance, with a station on the doorstep.
Small village, limited rooms, and they go early for race weekend.
Henley-on-Thames
More choice and a good base for exploring the Chilterns, with plenty of places to eat afterwards.
Around 12 miles from Goring, so it means driving on race morning.
Reading
The widest hotel choice and the best rail links in the area.
Around 10 miles away and not remotely rural — you lose the point of a Chilterns weekend.
Travel & Logistics
Goring & Streatley station is a short walk from the village hall, on the Great Western line between Reading and Oxford.
No Park & Ride. Parking is local to Goring — check the current race information for what is available.
None — the route uses the Chiltern Way, the Thames Path and other rights of way.
Spectator & Cheer Guide
Goring Village Hall covers the start and the finish. Because it is a single loop rather than a spoke format, seeing a runner mid-race means driving out to an aid station in the Chilterns.
The Chiltern lanes are narrow and parking at rural aid stations is limited. One mid-course stop plus the finish is the realistic plan.
