Wondering if you have guidance about what an ideal pace target would be.
Your pace will be what it is for you, today. An average pace does not help the slowest member. You cannot push unwilling or unable flesh up the mountain.
One 'rule of thumb' is that if you cannot talk and breath for climbing at the same time, then you are going too fast.
I always find it amazing that people rush up two flight of stairs and then start huffing and puffing. If they start at the right pace (slower) and breathing ( faster) beginning with the first step, then they can do 20 flights and keep going.
