Very interesting discussion! I have been riding for several years now but only just started running again recently. I love to run but as many of you have said, it's hard on my body and I get injured easily. That said, I wanted to start running again to cross train. So, I started very slowly building up my mileage and only after almost 3 months am I up to 3 miles- and I only run 2x a week. However as I started running longer Ive noticed that, when I ride, I can maintain a higher heart rate (160ish) for a very long time but when I have my HR up around 160 when I'm running, I feel like I'm going to die - what's up with that???
