Race Committee 16-6-21

The Chiltern Chase is a multi-terrain run, covering 5km, 10km or 15km. This popular course is based around the beautiful South Oxfordshire village of Ewelme. Runners enjoy picturesque bridleways and rugged trails of the Chiltern Way, accompanied by red kites overhead and occasional hare and deer. Running for over 11 years, The Chiltern Chase has raised over £100,000 for charity, and is managed by an experienced committee and supportive marshals. Refreshments are provided by Ewelme School PTA, so join us in a great day out for both runners and supporters alike.

    Race start

    After Marcus has done his pre-race brief can runners assemble at the Start line (big spanking new banner with “Start” on it) outside the pavilion where teas and yummy cakes will be served afterwards.

    • 5km – 0950am for 1000am start
    • 15km – 1005am for 1010am start
    • 10KN – 1015am for 1020am start

    The fastest 10k runners (sub 40 mins) are encouraged to start near the front and slower runners (60 mins+) towards the rear. 5k runners will be asked to start at the rear of the field. Your timing chip, supplied by Sports Systems, will give your actual time. Unless you expect to finish at the front of the field, there is no need to start at the front. The first race (5km) race is due to start at 10.00am promptly.

    Please note immediately after the start you will be on a public road so be alert for traffic.

    We love our course (and here it is!).

    It is a multi terrain route consisting of minor roads, private farm land (we have permission!), bridleways and footpaths.

    Race Finish & Results

    After crossing the finish line please keep moving to the finish area. There will be a number of us armed with cutters to remove timing chip from shoe, number or wherever you have fixed. Please seek us out when crossing the finishing line.

    From there you can collect your race medal, get your breath back and maybe have a cheeky massage from our on-site experts (a small donation for this service would be nice and it is very popular so there may be a wait!)

    Toffee, coffee and lemon drizzle cake as well as flapjack and shortbread awaits at the pavilion. And sweets!

    Provisional results will be available on the day and in due course they will be posted to our website.


    Toilet and Changing Facilities

    We regret that there are no changing facilities but we have great toilets (of the portable kind). Possessions may be left in the baggage horse box strictly at your own risk. We will keep an eye on them for you, but cannot guarantee their safety. Please present your race number to drop and collect baggage items. Toilets are positioned adjacent to the registration marquee. They will get busy just before the run starts so please be patient!

    First Aid

    First Aid facilities will be available at the event. Please ensure any important medical information is detailed on the back of your race number.


    We are proud to be plastic free again this year! Runners are encouraged to bring their own bottles. Water will be available in recyclable cups and/or for your own drinking bottle at the start and finish and at positions around the courses mentioned above.

    We welcome feedback after the event – good or bad! Please send your comments to Also, please also contact us if you'd like to help next year.

    Condition of the course and race cancellation

    The course is safe, albeit hilly, however in the event of a deluge or snow, prior to or during the event, things could get a little slippery on some of the off-road sections.

    Please take extra care on the off-road sections and be mindful of other runners.

    We regret that we cannot offer refunds if the race is cancelled due to extreme conditions as we will have already incurred all our running costs. As we organise the race to support local and national charities we ask for your understanding and support.

    The likelihood of the race being cancelled due to extreme conditions in June is about as likely as a smooth Brexit but you never know.
