We pulled data from the last four years of Long Jumpers to compare how Long Jumpers to their 100m Dash PR. We sorted athletes by their Long Jump PR and also added in their 100m Dash PR as well as their rank amongst the last four years Long Jumpers in the 100m Dash.
We see a lot of similarities in the girls data as we did in the boys. A lot of the top long jumpers have strong sprint speed, but the data would show outliers like, Kenyae Majors that would prove to be inaccurate. Majors currently holds a 100m Hurdle PR of 14.24, so it's safe to say she's significantly faster than her 13.94 100m Dash PR, which she only ran once in HS.
Leading these rankings is Sydnei Murphy, who was a star Long & Triple Jumper at Apex as well as an elite 100m Dash runner. Murphy was an All-American Long & Triple Jumper in HS, and wasn't too far off taking 10th at Nationals in the 100m Dash. Did he 100m Dash speed help her down the runway? Absolutely.
It doesn't seem like 100m Dash speed will directly correlate to being a strong Long Jumper. But with the right combination of long jump technique and speed down the runway, which doesn't even need to be for 100 meters, you can have a lot of success in the event!
