  • Did the Ultra in 2019

    Fantastic event. Great value for money and well organised! Couldn’t of asked for better. The medals were great and I will be back again
  • Did the Marathon in 2019

    Great course, was my first marathon which I probably could have chosen A slightly easier less hilly one, but loved it, and coming 3rd lady was just the icing on the cake. Would definitely do it again!
  • Did the Ultra in 2019

    Fantastic ultra through Kent. Really loved the course, not too many hills so as relaxing as 60k can be!
  • Did the Half Marathon in 2019

    Nice route, you can (almost)forget about the distance in your legs when you can look our over the water! Having both road and trail made for a nice mix.
  • Did the 10K in 2019

    Nice race through the countryside, well marshaled too! I did the 10K this time but I might be back for the half next year.
  • Did the Half Marathon in 2019

    I did the half marathon this year and it was fantastic! Very beautiful course and well organised, also enough of challenge without being too much of a slog. If I try a marathon next year it might be this one!
  • Did the Marathon in 2019

    Beautiful route in beautiful surroundings, good mixture of road and trail and a challenging terrain. Well organised and great atmosphere
  • Did the Half Marathon in 2019

    My husband ran so can't comment on the course except that he said it was challenging. However a few aspects of the organisation were really quite poor. You have to your race pack on the day as they won't post out in advance so you need to get there in plenty of time. The start is a significant walk away from the cafe area where you register. You were supposed to be at the start 15 minutes beforehand for the briefing but many people were turning up much later, obviously not realising how far they had to walk to the start. As a result, the race started a bit late. Only the people at the front could hear the briefing, the runners further back couldn't hear a thing or even the starting klaxon. After the runners went, the spectators started walking back towards the cafe area only to be faced with runners from the 10K event coming the opposite way shouting at them to get out of the way. There were no indications that there would be runners coming in, otherwise we would have kept to the sides. Part of the course actually ran on the same road as where the cars were leaving the car park, so as later runners were coming in, they were battling with cars coming the other way. This seemed very silly and dangerous and surely unnecessary. We then didn't see the results for another couple of days an only found out by accident that they were there. They were not on any of the organisers websites where previous years results were, the only way to find them was by a link buried in a previous email. Then to top things off, the photos appeared online and there was not a single one of my husband! Not one! Never experienced that before! This has the potential to be a good race but it is disappointing that after running for several years they have still not got their act together.
  • Did the Marathon in 2019

    Fantastic race. Great organisation both in advance and on the day, and lovely facilities at the Bewl Water visitor centre - nice loos with no queues, and efficient race number pick-up and bag drop/collection. Challenging but enjoyable trail route through beautiful scenery. Well-stocked aid stations. Will definitely run again!
  • Did the Half Marathon in 2019

    First time Ive competed in one of your events, well organised and good support at finish, already signed up for your MDW half in July!!
