While I don't have any inspiring stories to share here...I just wanted to say to Jiffer, that your post could have been written by me! Right down to the "gifted" DH and stronger cycling buddy...except my buddy is a 245lb male. Yes, a guy who has nearly 100lbs on me, can easily out-climb me every single time. It does get discouraging at times, especially since we both know that cardiovascular-wise...I am in much better shape than him. But I just do my best to try and keep up. I have to admit that sometimes though...when I'm lagging far behind, I do feel like breaking down into tears because sometimes it does feel pointless, as you said. Maybe we can inspire each other throughout the upcoming season.
