I believe so. Some of those guys were seriously rapid.
We were pacing at about 26/27mph going north from park square east and some guy just sprinted from the back, straight to the front and did a mammoth turn for about 3 minutes. I was in awe to be honest.
Was this the ridic quick one with the guy in the middle on the deep sections wishing he'd bought 40mm rather than double 88mm?
