BK - it's unfortunately called the L-plate runners(!), on at either Thursdaya at 8pm or Sundays at 9am, one of the gym coaches thinks it'll be a mixture of speed and endurance sessions, but other than that your guess is as good as mine! I'm going to sign up for it, as I might meet potential training partners (ideal for over the winter motivation), and it'll mean I get out at least once a week!
Phone Rivermead and ask for details
