The log for Stage 7 of the coming ToC is online:
At the fastest pace the racers will enter South Gate Road at 2:42pm and reach the Summit at 3:08pm.
At the slowest pace the timing will be 3:17pm and 3:48pm.
That's 16 to 29 minutes for the whole climb. I think the current record for the Diablo Challenge is around 45 minutes.
Am I hallucinating or are they riding on motorbikes?
