This week's spotlight turns to the indoor tracks and roads of the world, as we discuss the continuing recalibration of running performance. Every USA Men's Indoor distance record was broken in the course of a week, with two world records among the performances. One of those world records didn't last the week, as Jakob Ingebrigtsen broke it in France. Then on the roads, Jacob Kiplimo took the half marathon into a new galaxy with a sub-57 performance. The two-hour marathon is now clearly within reach. Gareth and Ross discuss those performances, and inspired to some Discourse, look back at a 2008 paper that analyzed race-horses and greyhounds to make predictions about how fast humans can still run. We check in those predictions to discover how shoe tech has moved some events ahead of the curve.

We also shine one last Spotlight on the Janik Sinner three month ban, elaborating on a few matters that arose since our previous emergency Spotlight, and explain why some of the vilification of anti-doping's process may be unwarranted, and in some instances (Tim Henman!) completely detached from reality!
