It'll be interesting to see what they do with the start. Could potentially make use of the PA and marquees and things in situ at the Racecourse and make it a really special start and finish. If you love the start at the castle there is always the Two Castles 10K in June. A few of our running group are taking part at Warwick. It'll be a good one I'm sure. Prefer Warwick v Coventry but shame they are on the same day.
With reference to Mike's post I'm starting to think I am more suited to speed work and lack guts/effort over 10K and Half perhaps. I did Birmingham last Sunday an whilst happy with my time (PB) I felt I ran too conservatively and may have just had more in the tank,,, my PBs
