Primary Outcome Measures

Name	Time	Method
To assess substrate utilisation using online gas analysis (Metcart) when running a half-marathon at an intensity representative of a race day. [Average respiratory exchange ratio will be recorded during each experimental trial, it will be recorded for 5 minutes every 15 minutes throughout the approximately 90 minute duration. ];To assess time to completion of a simulated half-marathon.[The time to complete a half-marathon will be recorded on the non-motorised treadmill during the study.]
