I see your point on Strava in Belgium.... <a href="http://app.strava.com/segments/search?utf8=%E2%9C%93&keywords=mur&cat=%3E%3D4&location=belgium" rel="nofollow">only 2 climbs defined with "Mur" in the title I can find</a>, and a French rider has the KOM up Mur de Huy!<br /><br />Anyway, Belgium is definitely on my "must visit" list, with Mur du Huy definitely on the schedule. It's maybe the best single climb in all the classics.djconnelhttp://www.blogger.com/profile/01484858820878605035noreply@blogger.comtag:blogger.com,1999:blog-1564958057737541664.post-45402879101183158462011-04-08T13:29:53.426-07:002011-04-08T13:29:53.426-07:00"I am extremely jealous of you riding on La P..."I am extremely jealous of you riding on La Palma...", :D ok, but except those 2-3 weeks/year that I can ride now on the Canaries, the surroundings here in Belgium (Flanders) are pretty much flat, I have to go for a 200 km tour to have a climb which gains more than 100 meters, or longer than 1 km... (on our training on Wednesday, we rode towards the more hilly regions, and we had still only 500 meters of ascent on a route of 75 km)... But indeed, the Canaries are very nice (I go back next in May, first work for 2 weeks, then riding for 1 more) :)<br /><br />http://connect.garmin.com/activity/54062920<br />http://connect.garmin.com/activity/53831679<br /><br />'for riders on "racing" bikes I think it's in the correct ballpark' - I agree with this 100%, that's why I really like the formula.<br /><br />BTW, I had a look on STRAVA and I like the idea behind it very much, but the number of users here is basically 0, so it is not that appealing to me...Péter I.

Spectacular!<br /><br />I like my simple formula, but the issue is it treats "steep" and "gradual" climbs differently. This makes sense, but the issue is different people may have different ideas about what is "steep". So I understand why Climb by Bike and Fiets go to formulas which don't involve any such distinction. This formula implies that climbs over 10% start getting much tougher, while climbs much under 10% the difficulty is more proportional to the altitude gained (whether that's less distance on a steeper road or a greater distance on a more gradual road). While this may not be universal, for riders on "racing" bikes I think it's in the correct ballpark.djconnelhttp://www.blogger.com/profile/01484858820878605035noreply@blogger.comtag:blogger.com,1999:blog-1564958057737541664.post-17606812114112065562011-04-08T12:53:05.535-07:002011-04-08T12:53:05.535-07:00I tested your proposed 'simple formula' on...I tested your proposed 'simple formula' on some selected climbs of La Palma (Canary Islands, Spain) to see what numbers I get, and I now understand why you prefer this over e.g. the Climb by Bike formula. Your numbers represents more the amount of work which you need to complete a given climb. If you estimate the relative power (W/kg) from the VAM with the rough formula here: http://en.wikipedia.org/wiki/Velocity_Ascended,_Metres_per_hour and then calculate the relative work by multiplying it with the climbing time, then the ratio of these 'relative work' values (Watt hour per kg) and the ratio of the values from the 'simple formula' will be much closer to each other, than the ratio of e.g. the Climb by bike scores of the climbs. So I definitely like it as a quick metric for climbs.Péter I. Pápicshttp://www.blogger.com/profile/03525973131351276087noreply@blogger.com
