Well worth event an race being tou get to run 600m through an old unused rail tunnel that's decked out in colourful lights....... awesome and totally different to any other race I've ran.
This isnt a course for the faint of heart or anyone that doesn't like a hill or two as it's pretty undulating/ hilly, but it's a beautiful course with some amazing views a great run for everyone.
Hints and tips, if its wet you really could do with trail shoes, when I did it it was pretty dry and I ran in normal road shoes, also if you want to race, choose the early start as alot of the 1st mile or two is single track with practically no overtaking.
There are several start times and distances for this race so a great run for most runners and if your quick and choose a later start time you can get a parkrun ran before hand although it is a 30+ min travel between events....... but a great warm up for your race.
All in all I'd love to go and do this run again and maybe go for the half next time.
