Aerobic exercises improve cardiovascular fitness

When training for a race, perhaps chasing the dream of finally getting that new PB, it can be tempting to embark on a training plan that focuses on going hard all the time.

This can mean you neglect the aerobic-capacity work needed to build endurance and a sustainable intermediate speed.

That’s where Critical Velocity (CV) training comes in. CV is a hard – but not-too-hard – running pace aimed at improving the aerobic capacity of fast-twitch muscle fibres, leading to stronger, longer runs.

This sort of training could help you achieve your goals without leaving you mentally and physically spent at the end of a training session.

So, how does Critical Velocity training work?

‘CV is about 90 per cent of VO2 max; but for the average runner, think of it as a few seconds per mile faster than your 10K race intensity, or an effort that’s sustainable for minutes,’ says Tom Schwartz, an elite US running coach and advocate of CV training.
