Adding a little speed work

I feel like I have a pretty good endurance base now, so it’s time to mix up the running a bit with some speed work. My goal isn’t necessarily to race faster, but just to add some variety to my running workouts.
There’s no track near me and since I hate intervals anyway, my plan is to throw in one, maybe two days of fartleks and tempo runs a week.
Should help with dropping a little more weight too (I probably need to start going back to the gym as well).
