Stadler's avg speed at Kona 2006

does anyone know how fast Normann Stadler averaged on the bike en route to a record bike split?

180km/4.27hours (4:18) = 42.15km/hr
.

26.13 mph for those types of people (myself included)
.

how much faster would it have been if he was on a P3C?

thank you all for your answers
