In pre-Garmin days (eg 29 October 2005) I think we would have done at least one 5k quicker in our 59km in 2 hours.
You have records in PG time ???
There used to be a thing called a Polar HRM. and before that a pencil.
I remember being thoroughly wasted after that ride from Dunsborough, which turned into a two-up time trial.
I thought it was an easy ride, well I was drafting you once we dropped the others
