Here is the interval workout breakdown: 3km warm-up, followed by 3x 2km 4:30 & 1km easy, and to finish off 2km cool down. I used my Apex 2 Pro by corosglobal to track this workout⚡️ *ad/anzeige #trainwithcoros #corosglobal #coros #intervalrun #viennamarathontraining #viennacitymarathon #marathonprep #hybridtraining
