  • Did the Half Marathon in 2019

    The race was pretty good with really good Pacers. The volunteers and marshals made it even more special. The instructions were all pretty clear. The only disappointment for me was no post running goodies (apart from the medal and a bottle of water) and not even a banana was offered after finishing a half marathon race. But, overall it was a fantastic event and the weather was awesome too.
  • Did the Half Marathon in 2019

    Very well organised, fast course and overall a great race. Need to start near the front if you don't want to get held up - makes for a fast start
  • Did the Half Marathon in 2019

    Great marshals and friendly atmosphere. Definitely one for a PB, not the most scenic but then again - its flat! Not so many people as to get in your way and quite a few pace makers for 300 odd runners if running slower than 1:35.Note: they set off a 5K, 10K and 15K shortly after the half marathon start and they run on the same roads - expect more casual runners (lots of headphones)
  • Did the Half Marathon in 2019

    This was my first ever event so was a bit nervous about how it all worked but I would say it was well organized and everything was easy to follow. So fully enjoyed the event. Thank you
  • Did the Half Marathon in 2019

    Fun run, superb marshals, though for a 35 run one costa van to keep all spectators ocupied for 2 hrs plus a little poor as was a tatty bottle of water with labels half missing for the runners at the end and a generic medal with only the ribbon to differentiate the runs a little disapoiting also. Plus not a banana in sight!.
  • Did the Half Marathon in 2019

    Great course, super fast and smooth. Perfect for a PB without needing to fight through the crowds as a fairly small event.No official results email though which is a bit of shame, also no veggie food on the food truck.
  • Did the Half Marathon in 2019

    Excellent race in great location. If you get the weather like we did its ideal for a PB. Great organisation
  • Did the Half Marathon in 2019

    Good course, atmosphere at some points could have been better. The lady who was by the bridge and cheering everyone on was amazing though!
