Perfect family race! No timing, no winners. A rolling start is really convenient with kids who want to just get started but who also don’t enjoy the rush of a mass start. The obstacles were all achievable and fun. Just wish they were spread out a bit more, as often there were four together then a stretch with none. Also note that parking and bag check cost extra!!!
Hi Jen,

Thank you for your feedback and for highlighting what you enjoyed about the event!

We’re delighted to hear you found it to be a fun, family-friendly race and that the rolling start worked well for you and the kids. 🎉

We’re sorry to hear the obstacle spacing wasn’t quite what you expected. The layout does vary depending on the venue and location, so some courses will naturally have obstacles grouped closer together than others.

Just to clarify regarding parking and bag drop, we do make the applicable parking charges and bag drop fees clear in our FAQs and pre-event communications, so participants have this information ahead of race day.

Thanks again for taking the time to share your experience, we hope to see you and your family at another event soon!

Best wishes,

Team UK Running Events

Enjoyed the day, a little sore after.
Hi Andrew,

Thank you so much for the fantastic 5-star review!

We’re delighted to hear you had a great day and found the event well organised and professionally run. A little post-race soreness is just a sign you gave those obstacles a good go!
