Well organised and nice location. Doing laps wasn’t that fun but that’s just personal preference and I knew I would have to do laps beforehand.

All excellent… course, location, parking, information, staff…. The flat course runs on wide tarmac paths by the rowing lake. I was delighted with the time I achieved. Great support from staff before during and after the event.

Excellent venue. Friendly and helpful staff. Great facilities. Will definitely be coming back again. The course is easy to navigate, and flat which makes it ideal for chasing a PB.

Friendly, well organised meeting (Duathlons and straight running races). All good. Flat, a bit featureless. 10k was the most chosen event with almost 200 entries. The 5k and Half Marathon also popular.

This was my first ever race (half marathon) so nothing else to compare it to. The facilities were good: parking, toilets and route markers etc. Staff/marshals were friendly and encouraging. It was the same medal for all the races though, which had a festive, somewhat childish design.

Arrived in good time and found parking close to start.
Friendly and efficient registration.
Clear instructions and a fast and flat we’ll signed and marshalled route.
I’ll be back.

Route was a bit boring, but it was doable and the medal was cool for completing the race

Simple enough to register, bit of a walk down to the start. Route itself was quite boring, essentially 4 laps up and down. Would have been better to run round the lake. Water stations at each end. No T-Shirt at the end as advertised and all
Medals were the same.

Arrived an hour before the start but the parking was full, cars were dumped all over the place including down the route. The start seemed pretty chaotic as there wasn’t really any clear direction. The run itself was fine, route was nice and flat. I probably won’t go back

Miserable start to the race, was made to park a 30 minute walk from the event village, then had to queue 20 mins for the toilet, just barely made it to the start in time.
Once the race got going it was fine, if boring. The view is of an artificial rectangular lake, not surrounded by trees or anything to look at. Will not be running there again.

Great course for a first timer, I did the half marathon and had a great time. The staff are great at encouraging you and everyone is so nice. I did find it a bit frantic at the start as so many events going on at once and up to 600 people plus guests there. The parking seemed to hold everyone up and a lot of people ended up starting later than the time slot. The staff were friendly and accommodated this which was nice as I was getting anxious that I was running late. Toilet queue is huge so get there in good time, bag drop is quick so do not worry about this. Enjoy the running, it's a great course!

Good flat course, would highly recommend for a first timer. The weather was windy and rainy but the staff and runners were unaffected. Directions were clear, there was a good range of runners and everyone was friendly. Good atmosphere, would do it again!

The course itself was nice - it's flat and open so you can catch a slight breeze. Just be sure to check your start times - my booking for the 10k said 9:30am but when I got there, it didn't actually start until 11am so there was a lot of hanging around for me!

Flat circuit for a swift run. Organisation was fine, but very busy at the start as so many events on at the same time; 5k/10/half/duathalon/triathalon/sprint triathalon. The 10k did not go around the lake, but was loops on one side; I guess because of cycling on the other side.
Shame no event T-Shirt included in package.
