We went on a sunrise cycle trip just over a week ago.
Even with the jet lag/time difference it was a struggle, it's apparently 50/50 weather wise if you actually see the sunrise. When at the summit we were told it had been 10 days clear followed by 7 days overcast and raining.
We started the cycle decent from a lower level due to the damp conditions and I was still underwhelmed by the view. Yes, I'm spoilt with views due to where I live!
The downside of the trip was my daughter came off her bike on a bend in the wet conditions and has now spent some vacation time in a wheelchair before progressing to crutches.
We are a family that road bikes as well as runs, swims and lifts but looking back felt very unprepared for the decent (you never need to use the pedals apart from possibly 2 small hills)
Be familiar with you brakes and urgent care/insurance number.
