  • Did the Half Marathon in 2019

    Lovely course, mostly flat is excellent for family and friends also for beginners. I have done it in 02:13 with a knee injury so challenge yourself to it
  • Did the Half Marathon in 2019

    Terrible, organisers couldn’t be bothered. Had to queue to pour a cup of water at the end. Few marshals on the return. No toilets. Paid parking.
