The Stour Valley Path is a 100km (62 mile) long footpath in England, which starts in Newmarket (Suffolk) and ends in Cattawade, a village near Manningtree (Essex).

The SVP100 covers almost the entire length of the well marked trail, and is one of the longest point to point races in East Anglia. The path is particularly notable for the beauty of the scenery en route.

The landscape on the Essex-Suffolk border was made famous by painters such as John Constable and Thomas Gainsborough.

The SVP100 is easily accessible from East Anglia, London, East Midlands and Stansted airport, and is worth 4 UTMB points.

A 50k version of the race is also available called the SVP50 and this race starts in Sudbury and covers the last half of the Stour Valley Path.

2020. Upon learning that my Chicago Marathon, I registered my first Ultramarathon SVP50 at a month’s notice as this was allowed to go ahead with covid safety policy in place. As I had not done any serious training for this I targeted to get from A to B without any emphasis on time and walk every hill. The organisation and the amazingly scenic route was well planned and clearly marked including a wee diverge due to a closed bridge. Water stations were placed a approx every 13 miles and provided plenty of nutrition and amazing group of volunteers. The undulating route was a mix of mostly trail, and road and easy going which was perfect for my first ultra. To be fair, I’ve already had 12 marathons under my belt in 2 years prior to this event so my body and mind was well prepared for it despite a gap of a few month's training. I loved it so much that I’ve gambled double or nothing and entered for SVP100 in 2021!

I have now completed this race 1.5 times.. I did the SVP50 last year and I really enjoyed the route and how well it was organised. I decided to come back for the 100 this year but sadly withdrew due to injury at 50km. With only a few hundred people taking part it has a nice community feel and you will get a very warm welcome at the checkpoints (which are well stocked) and the finish line. The event photos were especially good this year too! I will be back, not just because I have unfinished business but because it's a fantastic event. A huge shout out to Matt H and the team who do a fantastic job.

The SVP100 is a challenging, beautiful and greatly organized race. The information provided on the web page is excellent. I loved the frequent updates before and after the run. That makes you feel that you are really welcome as a runner and that the RD and his team enjoy the event at least as much as you do. The check point staff was also fantastic. Being runners themselves, they seemed to know what you need even before you knew it :-) A huge thanks to the whole team. I recommend this race to everybody wishing to master a 100k ultra on hilly trails in a stunning countryside.

I took part in the newly run SVP 50k Ultra. This was my first ever marathon distance or Ultra distance and if they are all run as well as this then I will be in for a treat. The organisation from the start was fantastic and the volunteers all doing there part brilliantly. The real heroes for me were the volunteers at the checkpoints, I barely knew what I wanted but they appeared to every time. Taking my bottles to refill them so I could concentrate on refuelling, thank you and I will be back again next year.

SVP100 is a friendly, well marked ultra across varied terrain boasting stunning views and a tranquil vibe. Checkpoints are well stocked and manned by local running clubs so the support from start to finish is fantastic. I loved every minute of this race and I can't recommend it highly enough.

Ran this in 2015. I enjoyed it so much I came back and volunteered in 2017. Fantastic event. Great route. Challenging and enjoyable from start to finish. Amazing support from checkpoints and fellow runners. A very special event.

I am a bug fan of this race having done it in 2016 and 2017 and I will be back aiming to win the black T-Shirt in 2018. Beautiful, challenging course through some exquisite countryside. Excellent checkpoints staffed by local running clubs that seem to try to outdo one another. The glow sticks for the dark sections were better in 2016 than 2017 but that's a minor quibble.

A lovely race and fantastic support all the way round. I think it's the best race I've ever done- certainly a great first 100k. The only real downside is there was no transport to get people back to cars at the start so if you're one of the slower runners (like me) and have no crew you're faced with a problem. But it's a brilliantly supported event with a very friendly atmosphere. Well done & thank you to the organisers & all the local running clubs involved.
Not sure if I've highlighted the stars but if it's gone wrong I mean 4.5 out of 5!

Great event, from start to finish this was a great day organised by a lovely young chap Matt, super check points awesome views along the course, they'll even give you a lift to the local train station when you finish. This should be on everyone's bucket list

A superb ultra marathon through beautiful countryside the SVP100 provides something for everybody. Often ultra runners are too quick to step up to the holy grail of a 100 miles and forget that there really are some cracking 100km events out there and this is one of them. Whether you choose to use this as your 'Big Race' for the year or as a 'stepping stone' for those longer ultras it will provide a challenge .
95% on trail, the course winds it's way from Newmarket to Manningtree with 7 aid stations along the route for tired and hungry runners to refuel and rehydrate. The event goes in two waves with the slower runners starting at 7am and then the speedier ones going for the prizes at 9am. This works really well I find and ensures that you see plenty of fellow competitors throughout the day.
The surfaces are varied as you'd expect from a trail race, including fields, paths, hills, with a fair share of nettles and brambles to keep it interesting and livestock to negotiate as well.
The route is excellent however I would strongly recommend either using GPS or ensure that you are a decent map reader. The wonderful volunteers at SVP do try their best to mark out the route and their are the waymarker signs to help you, but there are a few tricky places where it is possible to get lost if you aren't paying attention to the arrows spray painted on the floor.
Other than this the event runs smoothly from start to finish, and the atmosphere is fantastic. It is also spectator friendly with access to all the aid stations as well as several villages and pubs on route that supporters could stop at.
All in all if you are considering running a 100km event then I suggest giving this one a go... you won't regret it!
