Aivala's long jumping log

Yes, but at least this special field has been leveled to an extent with sand. Anyway sprinting there the day after a match is terrible. Not to mention normally the ride feels quite bumpy and you suddenly feel your hips dropping or after hitting a sand spot you kinda either slip or slow down. It’s like flying through turbulence. I am also starting to believe there is a very slight uphill there.

How much faster do your athletes run on a synthetic track?
