Organiser's Description

What is The Green Man Ultra?
Entries are now open for 2024

The Green Man Ultra is a 30 or 45 mile loop around the beautiful city of Bristol, following the distributed woodland of the Community Forest Path. The event is run by Ultra Running Limited and consists of four well-stocked checkpoints, chip timing, and pacers running at 9, 10, 11 and 12 hour times.

The race is run twice a year, once in the winter and again in the summer, offering two very different experiences of the course. The winter event is often muddy, providing challenging but fun conditions, and the summer event is more firm underfoot and faster to run. For added variation, the two events are also run in opposite directions.

Race Overview:

The Winter Green Man Ultra comes in two formats – the 45 mile distance and the 30 mile distance. Both races are held on the same course on the same day and have the same checkpoints and finish, just with differing start locations.

Both distances for the winter event will run the course in a ANTI-CLOCKWISE direction. This is different to the summer event.

Runners who complete both the summer and winter 45 mile events in the same year will additionally be awarded a prestigious GMU buckle. Four different buckles are available, awarded cumulative running time over both events – Sub 15 hours; sub 18 hours; sub 21 hours; sub 24 hours.

event info

All competitors must register on-line prior to the event. Collection of race numbers and a safety brief will be at the start location at least half an hour before the start of the race, where competitors will present their kit for examination on request.

Participants will be given a race number which must be clearly attached by safety pins. If this is not clearly visible you may be delayed at checkpoints.

The course is very challenging and for competitors own safety and fairness the following rules must be adhered to. Failure to comply with these rules may result in disqualification from this and future events.

The event is under race conditions and entrants will be issued with race numbers

Checkpoints will be provided (4 in total) to (a) monitor times & well-being of competitors, (b) provide water and some nutrition.

Check point cut-off times are set which will allow completion of the event within a 12 hour period. Anybody who falls outside these times, at any of the checkpoints, will have failed to have completed the challenge and not be allowed to continue. The cut-off times are as listed departure times for the 12 hour timelord.

All entrants must be 20 years of age or over at the start of the race.

Each competitor must ensure that they carry with them all mandatory requirements needed to complete the race.

Every entrant must confirm that they have read these rules and other event information and therefore understand the nature of the event and that participation is at their own risk.

At the end of the race finishers will receive (a) bespoke Green Man T-Shirt, (b) bespoke Green Man medal, (c) Signed certificate to confirm entitlement to either a Woodwose or a Woodwight (providing completion inside 12 hours).

Hot food will be available at the finish.

checkpoints & facilities

Please remember that the Green Man Ultra is a 'CUP-FREE' race, so you need to bring your own reuseable cup. We do have some GMU branded reuseable cups in our shop.

URL provide a selection of food and drinks to include sandwiches, jelly babies, malt loaf, crisps, savoury items, water, squash, coke, tea etc. The White Horse at Hambrook provide the food & drink at CP3 for the runners and the pub is open for normal fayre after 12:00. Competitors should cater for their own special requirements.

Example Food at Check-Points as 2020:

CP1 - Water, Squash, Cola & Maltloaf

CP2 - Water, Squash, Cola, Sandwiches and some cake.

CP3 - Ditto CP2

CP4 - Water, Squash, Cola, Coffee/Tea and Soup.


Competitors who have commenced their race cannot use the inside toilets at check-points.

At CP1 Norton Malreward Village Hall we will be supplying a Portaloo at the far end of the carpark.

At CP2 there will be a Portaloo in the carpark.

At CP3 The White Horse there is a toilet in the beer-garden where the food and water are on offer.

Please treat all Checkpoint Stations with respect. If you have any rubbish please use the black bags at that location - always ask a marshalling if you can't find what you are looking for. Littering is an automatic disqualification anywhere on the course, including CP Station.


In 2015 we introduced the timelords. These are entrants who try their best to run at specific times – 9, 10, 11 and back of the pack 12 hours. Any novice ultra-runner or person concerned with navigation can simply join a timelord who runs at their own race pace.

It must be noted that the timelord’s principal role is to offer navigation assistance and endeavour to complete the race within their given time period of either 9, 10, 11 or 12 hours. The check-point departure times are purely guide times.

A timelord has many considerations on the day including at least a 5 minutes stay at a CP for everyone to fuel and take a toilet break and ground conditions can play an impacting role also. A timelord may also choose to push harder at the start with a view to allowing a walk/run pace on the last leg – so there are many variables.

It may be that once a timelord has a formed group, the group unilaterally decides to increase pace and finish a bit earlier. On the flip side to this it may be that, during the later stages of the race (final leg), some members of a group require a slower pace which means the timelord arrival time may be delayed.

The only issue here is the 12 hour timelord position, because any finishers outside the 12 hour limit will not receive their certificate so the 12 hour timelord must allow sufficient margin to be within the 12 hour period.

If you are considering following a timelord add an hour to your expected finish time. The Green Man Ultra is notable as a tough and muddy course. If you choose either the 9 or 10 hour timelord, be prepared for a faster start than possibly you would expected. This is due to initial bottlenecks which are likely with so many starters and the obvious issues caused if the faster timelords were caught at the back of a queue.

Timelords will be conspicuous by having their hour marker flag attached to their back-packs. They will also be acknowledged during the Race Brief.

Timelord expected CP arrival and departure times

A Timelord will try to run at a reasonably consistent pace. The below times are a rough guide of where they will be when, in order to achieve their target times. Based on a 08:00 race start:

Please remember – these guys are all experienced ultra runners and have exceptional knowledge of the course. They have a really difficult task trying to pace their run to their allotted times. At the start they may seem to go off a bit faster than they should – but this is purely to avoid bottle-necks at the early stages.

The 9hr Time Lord will depart:
CP1 at 9.45am, CP2 at 11.00am, CP3 at 1.30pm, CP4 at 3.40pm and finish at 5.00pm

The 10hr Time Lord will depart:
CP1 at 9.55am, CP2 at 11.20am, CP3 at 2.05pm, CP4 at 4.30pm and finish at 6.00pm

The 11hr Time Lord will depart at:
CP1 at 10.05am, CP2 at 11.40am, CP3 at 2.40am, CP4 at 5.20pm and finish at 7.00pm

The 12hr Time Lord will depart at:
CP1 at 10.15am, CP2 at 12.00pm, CP3 at 3.15pm, CP4 at 6.10pm and finish at 8.00pm.


These are non negotiable and already include an allowance.

The only exception to this is the 12 hour Timelord who is the official back-stop, shepherding home the ultimate group of runners. Anybody who is with the 12 hour Timelord doesn't need to worry about time as he is technically "Mr Mop" at the back of the pack. If you find yourself at anytime behind the 12 hour Timelord then you are in serious trouble!

Please remember that the Time Lord role is to help you navigate the course in a particular time. In order to achieve the end-goal time, the Time Lord may choose to run the earlier stages slightly faster than the later stages, to compensate for tired legs later on!

If you arrive at a Check-Point after these times, for any reason, you will not be allowed to continue:

CP1 - 10:20am
CP2 - 12:05am
CP3 - 3:20pm
CP4 - 6:10pm

These times are not debateable.

Each participant will be given a race number which must be clearly attached by safety pins to the front chest. If this is not clearly visible you may be delayed at checkpoints.
Teams must have pre-registered before the day and consist of at least three competitors who will also count as individual competitors amongst the rankings. For a Team to successfully complete the race, a minimum of three members of that Team must finish.

You cannot change your race entry category or team once the race has started.

Relay team members: All originally designated members of a team must complete the leg they have chosen, and the following team member must not start the race until the person they are handing over from has arrived at that CP, otherwise automatic disqualification will apply. Changes to the team members and/or race order can only be made up until the team has signed in on the day of the race.

Competitors must go through all check points and it is their sole responsibility to ensure that the check point attendant has recorded their race number and entry/exit time along with any injuries; failure to do so at any check point will mean the competitor has failed to complete the race and will be disqualified.

All entrants must be 20 years or over on the start day of the race.
