The date 1066 is burned in the mind of everyone in the land. You all know the story. King Harold of England, fresh from defeating the Vikings in York, marched back to London, and then upon hearing the news of the invading William Of Normandy, gathered his Army and they marched South towards Hastings.

Harold pushed his men hard. They covered 30 miles a day (in armour!). The journey took three days, via Rochester and Bodiam Castle.  They arrived for battle, exhausted, and were beaten by William the Conqueror.

A long distance path called Harold's Way marks the battle-march route from Westminster Abbey to Battle Abbey.  You will pass all the best London Sights along the way; Big Ben and The Houses of Parliament, Tower Bridge, The Tower of London, The Millennium Dome, The Thames Barrier. You'll then go on to pass Castles in Rochester, Maidstone, and Bodium before arriving at Battle Abbey to finish under the Abbey's arch.


You will register for battle in London, along the banks of the Thames. You don't have the luxury of 3 days.  You have just 30 hours to replicate that famous march, and claim victory in the 1066 100 Ultramarathon!

Event Details

Battle Muster (race sign on!) will take place in from 7am, in West London at 

Barne Elms Sport Centre, which is a fantastic 52 acre Sports venue.







You will be issued with the following equipment:

Race Number

RFID Chip Timer

Race Drone GPS Tracking Device.  The trackers are the kind used for  D of E Tracking as well as Scout GPS Tracking, and general GPS Events Tracking.

The race will begin at exactly 9am, and end at 5pm the following day. English Heritage have generously permitted the finish line be under the Gatehouse the spectacular Battle Abbey, on the edge of the battlefield of Hastings.

It is a measured 102 miles (shorter and includes some faster ground than the 2019 route). The course is largely based on a long distance footpath called Harold's Way (but we have made some modifications for the next edition ). The modified route should be around 2 hours faster than the 2019 route. The route has around 2200 m of elevation. There is a 32 hour time limit. 70% of the route is off-road; this includes 20 miles of Thames Path, parks, farmland etc, 30% is tarmac road (mainly quiet country lanes).

In 2018 and 2019 we undertook a £1000 programme to update the waymarks on the route, after the Thames, with brand new "1066 Harold's Way" waymark discs, funded by your entry fee, to help promote use of the path to increase tourism as well as make help the event participants on the day.
