A break from the training to run some tests on triathletes from Leighton Buzzard Triathlon Club. Using a Lactate Pro2 and a Gene Active accelerometer, 20 triathletes ran a 12 minute Cooper test around either Stantonbury or Stoke Mandeville track. They have now been split into 2 groups of 10. One group will follow a 12 week triathlon training programme and the other will follow the same programme plus a selection of Natural Running Form drills. all triathletes will be re tested in 12 weeks on the same Cooper test run. We expect to see reduced vertical oscillation and an increased stride rate resulting in a greater performance run.
