Just got back from my morning run. I was in a rush and forgot breakfast which is a big no-go for me. So I decided to do a shorter 20 minute run but to try fartlek-ing. And on boy was that fun! It's really great to pick up the pace every once in awhile, and I haven't sprinted like that since grade school. I think I'll do these more often. My fast bits were very short, only a couple of light posts apart. Maybe I'll add a few longer ones next time.
If anyone had been considering running fast - go for it! I felt like I was six again!
One question though, should the sessions be shorter than a usual run? I was just as much of a hot mess as after my 35 minute long runs.
