As per title, let’s say my FTP is 288W. I train mostly indoor on a Kickr. I do outdoor 3 or 4 h rides on Sundays. Which they become chain gangs in the summer. Much slower in the winter.
I commute to work everyday (1h each way, 25km). I usually use it at active recovery.
What’s the best way to increase mitochondria volume during the Base training?
Sunday 4h steady rides at 65% of FTP? (Meaning average power 65% of FTP).
