It's an uphill strugglepublished at 12:29 British Summer Time 17 July 2016
What's worse than having to climb Grand Colombier?
Having to do it twice.
Well, one and a half times anyway.
That's what our intrepid explorers face today - one of the biggest climbs of this year's Tour, down to the bottom, and then halfway up again, before finishing.
Of course, if you wanted to make it really hard, you could get off your bike and start running. But that would never happen.
