Norfolk 100k

What an amazing race!! This is definitely one to be repeated!! Another well organised event from Positive Steps with some fantastic scenery and challenging terrain. Anyone looking for a good (challenging) 100Km this is certainly one for your diary........


Norfolk 100k

Think Norfolk would be flat, dull and un-challenging? Think again. The Norfolk 100k is one of the most varied and challenging 100k races I have run. It starts halfway up the Peddars Way long distance trail at Castle Acre, travels north to the coast at Holme and then follows the Norfolk Coastal Pa...


Norfolk 100k

This was my first ultra and a big step up from a marathon my previous longest race. It was very well organised and the organisers provided wonderful support. The distance had to be increased a bit because of permissions, and I went a bit astray a couple of times (my fault). I did 114k in the end....

V3K Ultra (Vegan Welsh 3,000s) (/Events/V3K Ultra

Vegan Welsh 3000s started out as an annual challenge for Race Director Kirsch Bowker and friends. Each year more runners joined, and the race has grown quickly, having become part of the Sky Running series in 2014. The V3k has kept that friendly feel, which is a feature of UK fell races. As Kir...



2016 marked my second comrades and my back to back medal. My 2015 (9:54) race was incredible. I think there is so much excitement in completing this event for the first time...your first time will forever be the most special one; 2016 (10:47) was not as incredible, but certainly taught a good few...


Richtersveld Transfrontier Wildrun 2016

My first ultramarathon - I was inspired after seeing some photos by Ian Corless, and seeing people who were less able bodied than me at the MDS talk. Only been running for 7months I wasnt sure I would finish. I did! it was truly unbelievable, the organisation/support, the food, the tents, the phy...


Marathon du Mont-Blanc

2nd year at this marathon for me, and again it impressed. Excellent race registration, and the volunteers and spectators were fab.People were out in force in the more accessible parts of the course, bells, music, horns egging you on. The scenery is just sublime and although it's a very demanding ...


The Great Barrow Challenge

Just completed my first Quad 4 in 4 marathons with the GB Team. This event covers 10 in 10 marathons, 4 in 4 & single days. There are 5 different routes - so I did the first 4, all are a mixture of trail & road - given the wet weather conditions this year - the routes were extra challenging. Thes...

Intro Ultra - Any tips?

I have signed up for a 50k ultra in July (first time at any distance over 26.2m). I have 6 marathons and several halfs behind me and will be doing a trail marathon in a couple of weeks as my last long run before the event. I have been training with a hydration pack and taking gels as I would normally in a marathon. My question really is as a rookie is there anything I should try to avoid/be aware of? As far as nutrition, should I be looking to take on more than gels, or will they be ok for this distance? Any tips or advice would be welcome. Thanks.

Marathon du Mont Blanc

Hello, Has anyone signed up for this and looking to swap hints and tips leading up the event? My husband and I entered the marathon with the results of the ballot being released on Monday. Already booked accommodation and lucky enough to arrive the weekend before to acclimatise (live at sea level). We're overdue a holiday so if we're not successful in any of the races we'll still have fun cheering others on.

First Ultra

Hi, I was reading the other post on first ever Ultra and have the same question, what is a good Ultra race to kick things off? I've run the London the past 3 years and train up 90miles/week and run a 2:42 marathon and was hoping this will give me enough of a base to tackle a 50mile. I've no idea if I can even run this long. I'm 50 in 2 years and saw the Comrades mentioned on the other post and would love to try that as a birthday present. Between then and now any advise on a good event to do, I live in the Manchester area but further a field is great too?

Ultra Marathons

Hi all, I am working as part of a team on our Final Year University Project, looking into the feasibility of setting up an Ultra Marathon event within the UK. We would be grateful if you could fill in the attached questionnaire about Ultra-Marathons, it should take no longer than 5 minutes and it would be a huge help for our research. https://qtrial2016q1az1.qualtrics.com/SE/?SID=SV_3ISwjdKiIavftE9 Thank you very much!
