Great route. Well organised. Well done Bev and Pete.
Nicki Benham
Another brilliant H&T event!
An event of two halves- canal tow path & seawall - bleak but beautiful!
Really well organised event as usual from H&T. Fantastic feed stations - especially the water melon - with enthusiastic volunteers. They always go that little bit further to make sure you have a good run. Thank you.
Richard Franklin
A lovely course and great organisation... and the medal was awesome! Will be back to try the longer distance next year.
Provisions in the goodie bag were excellent too.
Shane Ketteridge
Absolutely beautiful scenery.
If you want to be at one with nature then take on the Blackwater Trail Half Marathon. Aid stations are first class and will help you through as you take in some of the finest countryside Essex has to offer.

Lovely route with fantastic aid stations
Neil Suckling
Really enjoyed it. Friendly company the organisers were helpful
Would like more fruit at the aid stations, particularly if I was to do marathon or ultra. Okay for half marathon though.
Robbie Stevenson
Loved it
Steph O’Connell
Very well organised, friendly staff and a great route
The only thing I would improve is the printing on the front of the tissue. Only looks like it will last for one wear which is a shame.
Many thanks.

Fab support, lots of checkpoints with great provisions. Friendly team at H&T. Great medal T-shirt and goodie bag.

Ben Francis
Great event by great people
Would recommend this event to anyone.
Designed for all abilities and in its organisation means all runners will get to know each other.
Fantastic, well stocked aid stations with friendly marshalls. I’ll be signing up for next year as soon as possible.
And I’ve not even mentioned the scenery!
