Varied paced interval sessions ranging from 1 mile to tempo (half marathon) pace
Meet Lammas Park in the area by the Clovelly Gate entrance
[Steady pace or easy training runs are done at an aerobic pace, i.e. not too out of breath. This builds up the heart, lungs and legs but will not adapt the body fully to run at a faster race pace. Interval training trains up the different energy systems used in racing at different distances. These energy systems range from anaerobic running at mile pace or faster to ½ marathon training run at around threshold pace using the Frank Horwill 5 pace system system (used by Seb Coe etc).
To race at any distance you need to do intervals at race pace and faster and slower than race pace sessions. Also most club runners do a variety of distances and need sessions to train for these. With sessions done by time, any ability of runner is catered for from beginner to park runner to seasoned runners chasing faster times. The best part is everyone gets to rest at the same time]
