It's difficult to do a comparison of a 'Puffer lap without taking the weather into account.
When the 'Puffer Lite was being run in summer, I could knock off the same amount of laps in 12 hours as I was doing in 24 hours in the 'Puffer in winter, and feel a lot less knackered.
That's assuming we get proper 'Puffer weather this year instead of the tropical weather we've had the last 2 years.
