RFL was my first race too. I've done the Bradford one 4 times now however I know it can't be any more than 2.5 miles (0.6 of a mile is a lot to cut the course by) as my fastest time is 21 mins something. There is no way in a million years I could run 5k in that time! Based on what I know I can run, I know the course is considerably shorter than it should be. I'm now a regular runner and have done a few halfs and a full marathon and its disappointing that it's not the right distance, but I run it now to try and beat my previous best time, and not for a true 5k pb.
