The 26 mile, 385 yard distance is recognised globally as the standard marathon distance, but it wasn't always that way...

The first marathons had varying distances but a famous race changed all that: The London 1908 Olympic Games marathon ran from inside the grounds of Windsor Castle to The White City Stadium, finishing in front of the Royal Box. It was July 1908, a very hot day and the race started at 11.30am.

An original sign from the 1908 Olympic Marathon route - still proudly displayed on a wall in Eton.

Exhausted and wearing a knotted handkerchief to protect him from the sun, Dorando Pietri (Italy) entered the stadium in the lead. He went the wrong way, fell 5 times, crossed the line first but was disqualified following an appeal by the second-placed USA team, as officials had helped him to his feet.

Sympathy from around the world for Dorando led the Queen to award him a special cup. This race and the marathon distance became famous across the globe. The 26.2 mile distance stuck and has been the global standard ever since (although it was only officially ratified in 1924).

Every marathon ever run owes some small debt of gratitude to these legends of 1908.

A legacy event was established following this famous race and is still the longest running European marathon (only the Boston Marathon has a longer history). This legacy event (Polytechnic Marathon) ran from 1909 to 1996 and boasted 8 world records set on its course!

About the route

There are some small sections where roads have been built in the last 115 years, which do not have footpaths, where the group will deviate very slightly from the route.

Also it is worth noting that this event will be very slightly over 26.2 miles. The original 1908 route was on closed roads, whereas Original Marathon is not. The group will at times need to navigate roundabouts by crossing at pedestrian crossings, which can at times add a small amount of distance.

The Great Stadium Shepherd's Bush shows the number of medals won per country at the 1908 Olympic Games and is a fitting finish line to your historic run.

Way markers

The group will be guided and the route will be marked so navigation is not required.

Pace groups

The starts are arranged by pace group.

There are different wave starts, based on your predicted speed, as submitted on your entry. The event is a guided run but you're welcome to run outside of your allocated pace group. Your finish times will be listed and also compared to the finish times of the 1908 race. Results will be published and share. The first start will be around 11am. You will be notified of your start time/group closer to the event date.

Cut off time

6 hours.

Runners have up to 6 hours to complete the course, with the end of the event planned for 17:00.
