I LOVE coffee. But, it does increase my hr when I ride. I usually have 2-3 cups a day, but before a longer ride, i will drink tea. Plus, I find it dehydrates me when riding, not under normal circumstances, though.
Darcy, I have osteopeiniea, which is being treated with Evista. I do other strength training stuff and take calcium supplements/Vitamin D. No one has told me to stop drinking coffee. I asked about this, too. I have a feeling my bone density, while being genetic, is also being affected by cycling. Well, I am not going to stop cycling or stop drinking coffee. I COULD drink it all day long, but I don't and since I don't have too many other vices (yes, I love wine, too, but only a glass at a time!), so I will live with the consequences.
