General information

You choose. 20 miles or 20 kms (12.5 miles).
(You can transfer free from one event to the other).

As well as giving you the opportunity to go for a PB on a fast flat 20 mile course, this event may be useful to many who are planning on competing in a spring marathon - it will give you a good indication of how well your training is going and what time you are likely to achieve on the big day. The 20 km option gives runners the opportunity to try a new race length or use it for Half Marathon or Marathon training. 

This will be our 4th year and we are keeping the entry limit to 500 as we did last year.

This event is a few weeks before Brighton Marathon, Manchester and the Great Welsh and of course well placed for London, Blackpool, Stratford (Shakespeare) and Newport.

The 20 mile option is a two-lap flat course in lovely countryside close to the river Severn. The 20 km option takes in one lap of pretty much the same course. There is a cut-off time for the 20 mile route of 4 hours.

Access to the event HQ is on quiet roads and is only 6 miles from junction 14 of the M5. There is ample (hard standing) parking and the start of both courses are no more than 400m from the event HQ, which has good toilet facilities, changing and a baggage store. 

On the 20 mile route there will be 6 water stations giving bottled water - three different locations on the route that you pass twice and then a further one at the end. On the 20km route there will be 3 water stations and one at the end. None of the water points offer nutrition so you'll need to equip yourself with any gels etc. you may want on the course.

The 20 mile race has mile markers at every mile and the 20 km race has markers at each 5k point (5k, 10k and 15k).

Both courses have been officially measured:

   20 Km certificate
   20 Miles certificate

There will medals and T-shirts for all finishers.
Post race hot drinks and cakes are free to all finishers.

Chip Timing
This race (like all of our events now) is chip timed and you'll be able to see your time, position and category position projected onto a wall in the main HQ as soon as you have crossed the line.

In previous years this race has been permitted by ARC. We are planning to permit it in 2018 through UKA so that your results will appear in PoT and Run Britain databases.

20 Mile route description.

The start is around 200m form the race HQ. We gather on the road and then head off towards Ham without going through Berkeley itself. Then follows two loops of a circuit around Bevington Deer Park on very flat and quiet country lanes. There are 3 drinks stations which you visit twice - so 6 opportunities to take water on the course. After the two loops you head back via Ham, the way you came out and finish just outside race HQ. Water, t-shirt, cakes, hot drinks, medals and results displayed on a large screen await.

Nuclear Power Station

The power plant was shut down in the late 1980's and all nuclear fuel was removed in the early 90's. The decommissioning process will eventually be completed in around 2070. The Magnox reactors started producing electricity in 1962 - at the rate of 276 megawatts. The plant produced enough electricity to supply a large city like Bristol with all it's needs.


Berkeley Castle

The castle's origins date back to the 11th century and it has been designated by English Heritage as a grade I listed building. The castle has remained within the Berkeley family since they reconstructed it in the 12th century, except for a period of royal ownership by the Tudors. It is traditionally believed to be the scene of the murder of King Edward II in 1327.

20km route description

The start is on the roundabout right next to race HQ. We run through Berkeley village and then past the Salutation pub in Ham. Then follows one loop of a circuit around Bevington Deer Park on very flat and quiet country lanes. There are 3 drinks stations. After the loop you head back but at Ham cut back to the power station without going through Berkeley. The finish is just outside race HQ. Water, t-shirt, cakes, hot drinks, medals and results displayed on a large screen await.
