I am interested in split data for Gatlin’s 100 and 200m runs at the World Champs or another athletes 100 and 200m performances achieved at the same meet. The reason being I want to know the difference running the curve makes to the first 150m.
One of my 200m athletes can run 15.6 for 150 starting 150m from the finish but only 16.7 starting from the 200m start. Looking at the IAAF souces it appears running 200m on the curve is about 0.3-0.4 slower than running it all in a straight line see the website below,
I just want to know whether the difference in times can be explained by energy lost on the curve or that perhaps we need to spend more time working on bend running…
We made a decision several years ago to do as much of our speed endurance running on straightaways. We utilize a facility that allows us to run 100-150m without a bend.
The difference we have found is roughly .4 >.6 - depending on lane assigned on the curve. However, it was the transition of various phases that we remained with this approach. We believed that 30-40m and 60-70m sections were improved for the 200 event. At the time, it was thought that they applied the principles of those phases to the turn and eliminated the dreaded “push out-coast-setup the straight transition” that they were instructed previous to our work.
I agree. Although, in my area the curves range from 90 to 100m. We certainly do SpecEnd runs from the curve - so there are work bouts at max coming off.
In addition, we prep for 200m races with targeted curve sessions. Rarely over 90m though.
