Running economy : Energy cost per kilometre
RunThe oxygen consumption (ml O2/kg/km) required to run at a given pace : the lower, the more efficient you are.
Running economy measures how much oxygen you consume to cover 1 km at a target pace. Two runners with identical VO2max can perform very differently if one has better economy. Key improvements come from a higher cadence (~175-185 spm), tendon stiffness (plyometrics), varied-surface running, and functional strength work. In triathlon, running economy is especially important as the run leg starts on legs already fatigued from swimming and cycling.
In TriPaced:
In TriPaced, functional strength blocks and high-cadence sessions prescribed in the plan aim to improve your running economy, optimising your final run speed in the Ironman.
