Recently a good friend of mine: Edu has run the classic race known as Behobia.
It goes from Behobia to San Sebastian. 20 amazing kilometres in the north of Spain.
As usual, I decided to analyze the hills of the race with R and Tableau taking as input the GPS positions.
The profile of the race is the next one:
In the algorithm I have developed to detect the hills in the race, I apply a factor of 10%. It means go up 10 meters in 100 meters distance.
The result is:
So it detects the hills in the kilometer 6-7 and 15-16. But if apply a factor of 7% then the results is:
It detects the main hills of the race, so it indicates that Behobia is a difficult race, up and down and running to the goal…as life.
