Great Job man! I agree that running can suck it, but you did awesome!
for the first 10 miles I did respectably... then POW!
I dig the activity title, great job.
too fast start or too much h2o i'm guessing
Yeah, I started too fast, but mainly I have confirmed that I'm a weakling in the core. My abs are sooo sore today!
Yeah, could be from forceful exhaling (really deep breathing), or a lot of truck rotation.
