Full event info Keen As Mustard Bewl Water swimrun, held at the beginning of September each year. This venue is about 2 miles south of the picturesque village of Lamberhurst in the county of Kent, U.K., within an hour’s drive of Tunbridge Wells, Hastings, Tonbridge, Maidstone, Ashford, Eastbourne and Sevenoaks via the adjacent A21.
Bewl Water is a man-made reservoir set in 800 acres of wooded parkland. An ideal freshwater venue for a swimrun event!
Location
The event is based at Bewl Water, Lamberhurst, Kent, TN3 8JH, on the Kent/Sussex border.
How to get there
First, you need to get to the South East of England.
The closest airports are:
From these airports you can hire a car, head for the M25, take the M20, and drive to the Lamberhurst area.
By rail, you can travel from London to Kent by train. There
is a London to Kent train service with Southeastern services. London
Bridge, Charing Cross, London Waterloo East, Victoria and St Pancras
International all connect to Kent, with London St Pancras International
operating the High-Speed One service, taking less than 40 minutes from
the capital to the heart of the Garden of England.
If you are driving yourself from elsewhere in the UK, getting from London to Kent is relatively simple. Once on the M25, there are two directions into Kent; if you are coming from the North or the East, you will cross the Dartford Bridge (which has a toll charge). Once over the bridge, you will be in Kent, and you can follow the signs for the M2 or carry on down a little further to reach the M20.
If you’re coming from the south and west: on joining the M25, continue until you reach the M26 which will connect you with the M20. Equally, you can stay on the M25 until you reach the M2.
The closest main road to Lamberhurst is the A21.

Race routes
According to Keen As Mustard:
"The 6k and 10k courses head along the dam and out into the countryside before weaving their way back towards the finish. The 21k runs down from the start and the first swim takes you across in front of the dam wall. Catching up with the 10k course for the next few swims it then continues all the way around the reservoir. It covers some awesome trails, quiet roads and serious hills on a run through and around the nature reserve . Grass tracks take you back into wooded areas for a couple of swims before heading back around to the the finish. "
