I'm not sure if anyone does the same number-crunching that I do when it comes to their fitness workouts. I ran the BMO half-marathon for the first time this May 2018 and did ok but I think I would need to run the same course at least three times to get an average. I did the Scotiabank half-marathon this June 2018 and have run that same course three years in a row now. I don't think I can compare one course with another even though they equal the same distance. Here are my stats from the past three races: 2018 96/200 1:57 2017 76/194 1:57 2016 78/226 1:48 Average placement is 83/206 or at 60% fitness level when compared to a relatively fit population of runners in my age category. Is this a correct way of estimating fitness level?
