I signed up for it. Did the Rock and Roll Edinburgh half in 2012 and GNR in 2013 but not done more than 10k since then. Decided to start upping the miles again in case I either get into the VLM or decide to do Edinburgh (my local).
It's been fun upping the miles and re-learning the names of all the muscles and tendons that bother me after more than an hour's running. Attempting to do more cross-training and stretching this time round, and also build the miles up more slowly.
The legal bit is interesting (ref the fraud comment), hopefully there are some lawyers here than can put us straight. There's nothing in the Ts and Cs etc that says it's random, and I wonder if the use of the word "ballot" versus "lottery" is deliberate. This is a private event that you are applying to enter so they probably have a lot of freedom to choose, within the bounds of the law.
P.S. Here's my foil hat if anyone needs to borrow (kept in the office)
