 This page is intended to quantify and objectively compare the top bike climbs in the Owens Valley, California, U.S.A., French Alps, Dolomites and French  Pyrenees (see FIETS Index page for formula explanation). We were inspired to create this page  and the data assimilation contained on it in response to the debate (argument?) created over our suggestion that Owens Valley, California, USA is pound for  pound the greatest concentrated climbing region in the world (see U.S./Alps/Dolomites/Pyrenees comparison page for a broader comparison base).  We are not trying to advocate for any position on this page, or in this website, for that  matter.  The information contained on this page is for general interest only and is not intended to, nor does it purport to be, the definitive analysis or index for  top climbs in the regions documented  – this is really a starting point for discussion or debate (not argument) on the subject. 

 We strive to provide interesting and thoughtful information for cyclists passionate about climbing and who appreciate data related to such.  In that regard, we  appreciate and welcome input from all cyclists, particularly in refining climbs already listed, or adding to the existing list.  We encourage you to contribute via the Contribution Form at the bottom of this page. 


Our analysis leads us to the conclusion that  a 40 mile radius centered on Parco dell'Adamello, Breno, Province of Bescia, Italy has the the highest concentration of extremely difficult climbs in the world. Let the debate begin!  We welcome feed back, debate, assistance and, yes, even criticism, so please provide us your thoughts and alternative Top World Climb Zone by using the Contribution Form below or emailing us directly at john@pjammcycling.com.

 Thank you and we hope this page is of interest and use to you.
