QOTW: So I was recently playing around with ways to express my race data, and found a method that looked interesting. Converting all my race times into Daniels VDOT values. This way regardless of distance (mile, 5k, 10k, HM, M), they were all expressed using a comparable numerical value. With the understanding that Daniels VDOT is a sort of "race equivalency". Such that a 4:00 marathon, 1:56 HM, 52:25, 10k, 25:15 5k, and 7:29 mile all give the same VDOT value of 37.9. It also "squished" my Dopey results into a downward linear line which didn't disrupt the overall visual appearance. It was an interesting way to express the data for me to view.
So I was wondering if others would be willing to share what their VDOT race progressions look like. I'd suggest only using races in which you were actively racing hard. Having races that weren't for the purpose of extending yourself probably would make the information harder to interpret. Certainly there's going to be some bounce due to the difficulty of the race environment and course as well, but those things will easily wash out in the big zoomed out picture. You simply plot your date of race against the VDOT value of the race using Daniels calculator (

Where my curiosity lies is when you personally saw a plateauing of progress (or haven't yet) and ultimately what was your VDOT % gain from start to peak. Word of mouth data (which I have yet to find a paper verifying) states VO2max can increase by about 5-15%, or 40%, or some other value in untrained runners to their peak condition (
link). VO2max and VDOT are not the same, but I do believe they rely on a correlation relationship as VO2max is one predictor of race performance. Additionally, plateauing of endurance performance gains is suggested to occur around 7500-10000 career miles. Although there is some lagging in your ability to be a good converter from shorter distances to longer distances. So I wanted to see what we showed as a group.

This is my graph. It goes from my first run in June 2012 to my peak performance in Jan 2018 to my most recent races.

I saw two jumps in performance. During my first time using Hansons in 2015 and when I integrated Daniels methodology in the Spring of 2017. But ever since I hit around 7500 career miles I've seen a steady plateauing of my race VDOT values. In total I went from a VDOT of 24.7 (first run), 29.9 (first race), 52.1 (best VDOT in Jan 2018). So my total % gain was (52.1-24.7)/24.7 = 111% from my first run and 74% from my first race. The span from start to peak was about 5 years. The last 3 years have been roughly at the same level.
