Runalyze is one of the most data-dense training platforms available — a deep set of derived metrics and long-run trend analysis for athletes who genuinely enjoy digging through their own numbers. That density is its strength and its cost. ActivityStat surfaces a much smaller set of numbers, in the place you already look.
