> The current setup is more akin to a 100m running challenge where he was allowed to run 50m before starting the actual 100m to get up to speed. It looks like an interesting idea. The long jump competitions have something like that. Can someone organize it? Do you have to go slowly the first 40 meters and increase the speed just in the last 10 meters before the start line? Can the data from the 200m run be used to estimate this? |

And it is absolutely the case that the times for world class second-100m of a 200m sprint are generally lower than even world record 100m sprints (in that report above, out of the field of 8, 6 runners beat the 100m world record over their second 100m)
Usain Bolt's world record 100m from a stationary start is 9.58s. His world record 200m splits were 9.92s and 9.27s.
Over the middle 100m, his time was 8.84s.
(see https://speedendurance.com/2009/08/21/usain-bolt-200-meter-s...)
So yes, a flying start makes a massive difference. 200m runners are generally slowing down in their second half (Bolt's last 50m took 4.75s, while he covered 100-150m in 4.52s, and 50-100m in 4.32s), but their average speed over the final 100m is still faster than a 100m runner. In a 100m sprint the runner may still be accelerating by the time they reach the line.
