This was the 2nd time I had run the Bath Half and this year I was aiming for a sub-2 hour PB... the rain came down and made it reasonably miserable by the end, but success was mine!
The course is 2-laps and as such by the second lap, it's quite boring, especially when you've run the race before. That being said, despite the rain, the locals were out in force cheering for all the runners.
The downside to the race is that because of the closed roads, Bath is a logistical nightmare to get in and/or out of on race day. The best option is to park elsewhere and go by train if possible, or be aware that you will be walking quite some distance before/after the race!
