The average for the whole 82 minute ride was 131 -- but that doesn't include the last 17 minutes on a down hill where it dropped well below the 120's.
So, is it 131 averaged over 82 minutes or over 65 minutes?
In either case, this would suggest that your heart rate at LT is at least 130. This is reasonable for a 63 year old. This would also suggest that your %VO2 at LT is 70% or higher. Normally LT = VAT (within the margin of measurement error). I think there was something wrong with the ventilatory test.
