In a team, it takes everyone to up the tempo but only one to slow it down.
Imagine running in a group. If you want to go faster you need everyone to go faster. But if one person starts to slow down, the only way to hold the group together is to all slow down. (Rowing is probably a better analogy, but I’ve never done that).
This is frustratingly obvious in many ways.
But I think it’s easy to forget — I sometimes find myself trying to up the tempo by pushing my pace harder — Then I look back, and someone’s only further behind!
Instead, if you want the group to go faster you have to slow down and coach those going slowest. (And sometimes they need to drop back to a slower group).
