Hi Liz! I can recommend Peloton. It’s pricey but has something for everyone (recorded and live classes, different instructor personalities, various workout types) and is fun. They advise combining running with strength training - exercising your legs helps as much as training endurance itself. 🩷

Sorry for having missed you :/

I take this as an invitation to a (re-)visit of your lab, Claudio! 😀
