I live in Lugo, a small city in Galicia, Spain. Even though there are lots of mountains in my region, not too high but mountains, near home it's difficult for me to find routes with a significant amount of positive meters. For me, this is always a challenge to design a route with, for example, 300 positive meters. So, it would be a great challenge to complete a vertical kilometer in only one activity. Probably, for me, in my city, I would need about sixteen kilometers at a specific loop to complete the VK.
The idea would be that every month, among the different challenges like a 5K, a half marathon, or completing 2000 positive meters, to find a VK in only one activity.
I would be glad to know what you think about this.
