Little background on me: I'm a casual Ingress player. Ingress is a AR mobile game developed by Niantic, the same people that made Pokemon GO.
Due to having little free time and money I can't go to anomalies, which are big Ingress battles that take place in various cities.
The day before an anomaly there may be a fitness challenge sponsored by GORUCK, a company that sells tools for certain endurance sports.
My medium/long term objective is to grow in salary and physical strength so I can partecipate in one of those events.
