I just finished a 22 mile ride around Creve Coeur Park starting and ending at the Missouri River bridge. When I turned off my Garmin I found a read out that said 853' of ascent. 853'! Can that be true? There are some contours on the route that I rode but certainly nothing that I would call a real climb. Could 22 miles worth of those little ups add to 853'? Is there a reset button that I don't know about?
