<human>: Hi Guys!
I'm 20F and have been running since I was 15, never for track or xc, just for fun/exercise. My best friend and I (also 20F) usually run together and we're perfect parters: we can both run long distances (10mi or so) without any problems, but we are SNAILS. No matter if we're running 2 miles or 12 miles, it is always at a steady 10 min/mi pace. I don't mind that we run slow, but recently I have been running with my boyfriend who is a foot taller than me, and naturally just runs faster. I find myself having trouble running more than a mile and a half with him, but he can't run at my pace because he'd basically be walking. We're doing the Peachtree Road Race this July (10K) and I want to be able to run it with him at a faster pace. 
What can I do to fix this?

Give me a shortened version of the text
<bot>: I run a 10 min/mi pace, want to start running with my boyfriend who runs a bit faster, but I am having trouble running faster for long distances. What do I do? thanks!
