Hi Gill

It looks like you have  the route name as slightly different each time - your first entry has an extra zero.    PBs are only picked up if the route name is exactly the same.    So, if you search under Bupa in your log book you can find your previous entry for this race and edit the route name to the same as the recent one and then your PB will be picked up.  Well done on the PB by the way!
