I realize that this post is going to read like it came from a decade ago, but I'm kind of stuck there given my current bike setup and available funds.
OK, so about ten years ago I started swimming, biking, and running for fun and casual fitness (did a handful of actual tris early on, but haven't done one in a long time) . I've never trained with HR (or a powermeter - too much $$$), and fast forward to present, I bought a Garmin Fenix 3HR on Black Friday because I wanted one for GPS running, biking, hiking, etc. I also liked the fact that if I'm able to buy a used powermeter next year, it'll tell me my numbers. I've now received the Fenix and slowly learning how to use all the features. What I would like to know from the collective ST community is what are the best sources for information about improving my fitness while training with HR numbers. Is there a great book/website that you would recommend that explains how best to improve your fitness level by doing certain intervals or training in various HR zones. Right now, if I do a run or bike ride, I can see my graphs of HR and pace, but I have no idea how to correlate that info into actually improving. Right now, I'd like to limit it to HR, but I'm sure I'll have the same question if I ever buy a powermeter and want to start training with those numbers. Thanks in advance.
