As always, Tom and his Team delivered a great event. It feels like a family run race rather than a big corporate event. Well organised with good marshaling. Only 1 thing I'd add is a 100m to go sign at that timing marker as you approach the finish. I saw many less experienced runners clicking their watches and actually stopping until we all screamed at them to keep going. Thanks again Paul Thomson Elmbridge Road Runners

Amazing event - brilliant info before, during and after; super volunteers; phenomenal (free) photographers. Best goodie bag ever - full of healthy recovery items and so packed too! Thank you!

Fantastic event with seamless organisation, a great medal and goodie bag and free runner photos too - superb! Just a shame that the council charged £6 to park in the Heart MSCP instead of the expected £1 on a Sunday!!

It was an enjoyable run but it did fall short on a few aspects. The post codes for parking were useless, there was loads of people driving around doing U-turns so that could've been better I guess. There was no running pacers to give you an idea of your finish time, which I found really helpful on a couple of other runs. The bag drop was not secure.... i saw people freely walking over to bags and collecting them without any checks, so i wouldn't use that. The congestion at the start wasn't great..... needed a longer distance to spread out before getting to the public pavements. The course marking was clear though, toilets on route was good, plenty of water stations and the marshals were very friendly.
