I have heard the advice to make slow runs truly slow and hard runs truly hard, but I hadn't really run slowly enough. So I set my watch to heart rate instead of pace this morning and tried to stay in Zone 2. It was so hard! And boring as hell! Even the dog was bored and looking for squirrels to harass. Runners, how do you endure Zone 2 slow (not medium-paced) runs? Podcasts? Music? Zen states? Or did you just get used to going slow after a while? Or give up on it? Advice welcome! #running
