One last question. The RAe workouts say that zone X is acceptable for advanced athletes for the 15’ intervals. Is it ok to push these intervals to the top of Zone X if that’s your anticipated race pace? Thanks!
Yea you’d be correct, should’ve included that. Last 70.3 race I ran 7:16/mi for the half marathon on a course with around 375’ of elevation gain. My next race has less than half of that. I’m looking to get to that 7:00 pace.
