Course Maps


Being on the newly developed seafront there are loads of good vantage points, with seats for spectators. There's a local crowd and plenty for family and friends to do after the race.

Apart from the above, you will get access to the Sunderland Marriott Hotel which will have a meet n greet hall with room for all to chat away those nerves and keep warm. It also has ample toilet facilities.

There will be a souvenir video available for high res download to show off, and you will also get a simple link to share on your Facebook, twitter etc. So, everyone can see what you achieved!! Ideal for charity athletes. All being well - your video will show your name as you cross the line.
