Very very nice website. Lovin the photography, typography and concept.
I don't know what to say about the photos. I'd change this one: https://dl.dropboxusercontent.com/spa/9xf6wkaibabfmez/yjs4bc80.png
I really like the design EXCEPT the "features/premium" navigation. The font they used feels off to me and I think it's a bit lost the way it's been positioned.
Lovely website, app is great too.
Few months ago Strava changed their mobile app theme from dark to light, with no possibility to switch between them. When announcing the change they were using terms such as "extensive UX research" and "thoughtful design decision"... which of course was not taken for granted among users who are a bit more design-conscious than Strava would wish them to be.
I'm not sure I've seen a design critique of the current app but it's definitely a nice example of how to ruin user experience with a relatively simple change.
Nevertheless, the app does its primary job, and the refreshed landing page looks nice.
great work to the strava team!
