I am wondering what is the correct pace for easy runs and long runs. some say 60-70% of max HR. Daniels who is one of the most rspected coached says 65-79%.
if i want to do a marathon late in the year i assume i need to work alot on this easy running as base phase to work on the fat burning aspect that is so important for marathon?
Daniels 79% seems quiet high? even pfitzinger recommends up to 75% of max HR. so seems to be varying guidance on the correct range for that goal of training.
Wiuld love to hear your views on the best heart rate zones to work on for marathon?
