This was the first time i ran this race. I wanted to do it because of the chance to see parts of the city of Bath you nomaly wouldn't. Once you pick your numer up you are put in to waves of a 100 runners for safety reasons as once you get to the tunnels you Have the wave before you running back to the finish. On the start line you get a quick warm up and chat on wot to do.. You have a start on the grass of a 100 meters before you get on to the old railway line. . It is now one of the main bike track to bath and Somerset with manly tarmac.. There two tunnels you head for like in he name. The first one comes just after 1k, it's not to long around 400 meters. You come out in to some lovely woods before the next tunnel which is a lot longer with a bend in it. When you come out the other end this is where you find the water Station and 5k .Mark. All you got to do then is return the way you came ,the finish has a small hill of 50 meters not to bad. You get given your medal and water and goodies chocolate heather things.. All in all a very well run and enjoyable friendly race. I do it again.😁
