How much of an impact does wind have on track and field?

Can the wind levels actually have a large outcome of the races time?

Of course. There are calculators out there for you Google them that approximate the effect.

Obviously the sprint events have the biggest boost from a tail wind.

Lj, tj might have the next biggest benefit.

Hurdles and PV would get the least boost, but still a potential boost, although some hurdlers hate a tailwind if they already tend to be crowded.

Disc can actually get a benefit from a slight headwind.
