London - last time I will be posting from home for weeks

From last week's experience - learn to drink on the move.

I was riding with folks who don't like to reach down and grab a bottle whilst still rolling. Multiple snags:
Stopping starting is huge effort on long ride.
One drinks less regularly.
You lose cooling effect and immediately sweat up.
Stops are when you need to drink not in nice cool spots

And
Sunscreen & correct clothing
Efficient riding
