Heart rate and pace over time within a particular run, or heart rate and pace over time across many workouts? For the first, if you have something like a garmin, yeah, you can upload a run, and see a complete graph of your heart rate and pace during the run. For the latter, yes, you can use the reporting features of this site to graph that. - Select the training log tab. - Click on reports. - Click on new graph. - For the X axis, use date. - For the Y axis, use pace, or average heart rate, or whatever you want. As long as you record the stats for each run, you'll see what you want. If you view the post I started just below this one, I embedded graphs of both types into it, so you can take a look at that for an example. Hope that helps.
