Storage will be available in a designated baggage area at the start/finish. Runners will drop off and collect their own bags, but stewards will monitor the area. The organisers regret we cannot accept responsibility for security and advise that competitors do not leave valuables in their bags.

There will be very limited changing facilities and we therefore recommend that runners come ready to race.

Portaloos will be sited at the start/finish.

Unfortunately, there are no shower facilities.

As well as your race number, you'll find a timing chip in your race pack (available to collect from a local collection point before race day, see entry tab, or at the start on race day). Follow the instructions for attaching it to your running shoe. Your chip will be detected as you cross the start and finish lines so you'll get a personalised time. Please make sure that you return your chip after finishing the race.

Professional first aid cover will be available to provide medical support if necessary.

On completion of the race, drinks and food will be available to purchase in the pubs and cafes in nearby Walton-on-Thames town centre.

We have water stations at approximately 3 miles, 7.5 miles, 9 miles, 12 miles and at the finish

You can collect your race pack on race morning or you can collect them at Weybridge Sports from the 9th October. You will be emailed final instructions closer to the race.

Weybridge Sports 44 High St, Weybridge KT13 8BL

Pin your race number on the FRONT of your running vest or ‘T’ shirt, where it is most visible for race officials. Runners who do not have a properly displayed number or are identified as running under the wrong name will be liable to disqualification.
