As your physical range changes, your starting position becomes more important.
Try to arrive in useful spaces earlier rather than solving every situation with a recovery run. Stay connected to the part of the pitch where the next pass is most likely, and avoid being drawn towards actions that another teammate can already deal with. A few yards of better positioning can save a much longer sprint later.
In possession, choose moments to go beyond the ball rather than joining everything. You can still arrive in attacking areas, but the team may benefit more from you controlling the space behind the attack on some phases.
I would not automatically move deeper just because you are older. Adapt the role to what you still do well. Experience should help you recognise the next problem sooner, which is often more valuable than trying to match younger players run for run.
