Looking at the times of both horses and humans it seems that the main problem of this race is lack of professional competitors. When I see that the horse rider won by covering 35 km distance in 2 hours 40 minutes (on some years)then I think: that would be beaten by any professional marathon runner, who tend to beat that time on longer 42 km distance.
