Thanks man!

It depends: during this run where it went very well it made it so much easier as I knew I had it from 15km onwards that was sufficient margin that to just cruise if I had to. But with my November 2025 marathon where I did not manage to hold the pace after 7km it was hard to have a constant reminder for another 35km that you are not running in line with the plan.

For the sub 3 attempt I will probably use it! Currently considering this pacing plan - only slightly negative splits.
