5 weeks to go before the Apennines, time to do some hills. Overtaken with 5 miles left by a pair of sharp-dressed (Rapha/Castelli!) riders on lovely machines, went by so quick I gasped. I didn't even think about trying to catch their wheels, I was shot. They then slow dramatically, and I am rapidly catching them, so I put my head down and fly by. I give it all I have to the top of the Pike and let gravity take me down the other side; I think I can hear them behind me, but won't look back. As I get ready to turn off the main road, I look back and there are three or four of them about 100m back, so the first two must have been waiting for club mates. But I don't understand why you would overtake and then slow to a crawl?
