Well there were four of us.
Certainly is, especially following an interval session.
Wow, impressive. Did the wind change at the turnaround so that you had a tailwind both ways? (I'm sure you're just uber-fit!)
No we had the tailwind on the return, not going out. After I left the guys at Raffles I had to ride back into it, at least heading south. Heading east-ish towards home was a cross wind.
