Sonia explains the difference between and easy and a "regular run". It's a subject that ex-elite athlete, now elite physical therapist, Vinny Mulvey and I have been exploring for the last 60 days. For the London Marathon 2024 I'm running for Kidney Care UK and I'm using low heart rate training to build the aerobic base that failed me in Dublin last October. So far it has been a revelatory experience. At first, mind numbingly boring, then agonising, then joyous - the process of learning to run properly slow on my easy days has not been easy. Vinny takes me on the Seb Coe loop of Ashbourne, Co. Meath to explain some of the more difficult questions surrounding low heart rate training.
