Kryton makes a good point.
& when you combine your physiology with an optimum weight then you can really fly!
I’ve never had great power but I’ve always had good stamina. At my best I was finishing in the top 10 at Brass Monkeys 4hrs & top 5 at Bristol Oktoberfest. The thing is I was never that quick – my lap times over those races were just consistent. My coach & I did try to up my peak power by doing shorter XC races…..I got totally dusted at those!
It’s about playing to your strengths.
