The Greensand Country route is considered to be a fast and accessible ultra marathon. We have seen lots of runners compelete this as their first ultra. The paths are good quality throughout and free from soft mud at this time of the year. The heat can present a challenge, but this is of course never gaurenteed in the UK.

I'm worried about getting lost?

Our route will be marked throughout with orange signage/ribbons, along with marshals at several key points. Course checkers will be out during the race ensuring that signage remains in place.

We ask runners to make sure they have access to the route via a phone or watch, to act as a backup in an emergency.

Yes, there will be several pop-up changing tents at the event base for runners to use.

How can I attend this event without a car?

Biggleswade is the closest train station to our event base. From the station it is a short 13-min taxi journey or and 11-minute cycle. We will provide a safe place to store bikes whilst you are running.

We would recommend a light trail running shoe for this race - something that can tackle varried and uneven terrain and remain confortable on harder dirt paths.

There are awards for the top three male and female finishers overall, along with age category awards for FV40, MV40, FV50, MV50, FV60, MV60, FV70, MV70.

How do I follow the route using my phone or watch?

Most GPS watches allow you to upload a GPX file of the route for you to follow whilst running. Typically this is done by loading the GPX file into the app (i.e Garmin Connect), and then syncing your phone/watch together.

If you don't have a GPS watch we would recommend using OS Maps (£20/year) or Strava Premium (£48/year).
