Easy parking on site and open to public so family and friends can come for support.
A small field for the 10k which I took part in, of about 150, so it was nice and easy going with plenty of space to run around the paved paths of Dorney Lake. A lovely venue for this race. The course is a full lap around the lake, with a lap on the outer then inner loop to finish.
Chip timing with immediate results available, and worked well.
Water at 5k was provided and marshalling along the course was good for me. Photographers along the route also. F
or a runner of modest abilities like myself this was a well worthwhile event, which I enjoyed and set myself a 10k PB. Would recommend Fix Events to runners of all abilities. Thomas H
