Over any given year the sessions offered follow a traditional pattern with the aim of bringing up members fitness levels to supplement their own training regime.
Basically, late September to February the following year will be Endurance and Strength work (long repetitions, hills and cross country events). From March onwards the move is towards Endurance and Sprint work, sharpening for the new season including Summer Road League, Club Championships and the multitude of events you can find in the running calendar during the Spring and Summer periods. In the racing season some Endurance work is maintained but shorter reps etc. are introduced to keep you sharp for racing.
Sometimes we move away from the regime to accommodate specific events such as the Bed Race or some individual races where I know there is going to be a good turnout of members OR just to give variety.
