Phew! Just got in #426. I have already booked an entry for the Tour d'Etape on the 8th July and as I will be retired by then, the time in between that and the 4000 is my own.
I did the Stelvio when I did TCR02, so I had the ride from London in my legs and didn't find it too bad, just long and bloody cold at the top - it was raining hard. It was tricky going back down the same way, I had just put on new brake blocks and they were almost completely useless in the wet, so I went off the end of the first hairpin - harmless but tiresome, thus I had to take it really slow until the bends ended.
