Impossible results: June Run Climbing Challenge
Could you look into the June Run Climbing Challenge?
The results of the top ones are simply impossible. There are even some activities with gains of 18.000 m in 11 km like this one
Looking roughly into the figures, I would say that the top 8 have miscalculations in some of their activities
I would recommend you to set up a sort of "internal alarm" based on ratios (you cannot climb 1000m in 1 km) in order to avoid these issues.
Thanks in advance!
