Fuck me, every Saturday I do a long distance run gearing up for half a marathon in november. I'm up to 16km atm and the hardest part is crapping. I try to go before I go out, but can't and then around the 45-60min mark I feel a heavy deuce coming up . I could go faster, my legs are good, my longs and heart even better...but it's so hard maintaining a good pace when you constantly have to barricade your shitter, pulling back the troops. This week was difficult, though not as hard as last week.
BUT THEN, when I finish that run and run to the toilet...my oh my. HEAVEN. Recovering from that long run X shitting =

Almost makes it worth it.
