exercise woes

last thursday night i went swimming. it was late for me - i went around 9:30 pm. the first thing i noticed when i got into the pool was how cloudy it was. i couldn't even see a foot in front of me. gross. but i was already in and wet with my rubber cap on so i decided to stick it out. my swim was pretty good ... except ... when i was almost done the security guard came and told me i couldn't be there. what in the world? he then immediately took it back and said i could be there. what was he talking about? well, he explained later than he thought i was underage because i looked like a little girl in the monitor. i don't know if i should be flattered or weirded out. a little girl? true - i do use a baby blue kickboard with a grimacing shark on it ... but what the hell would a child be doing pumping out laps at 10PM on a thursday night? riddle me that!?

the next time i tried to swim was on saturday morning. i was going to run but wasn't feeling too hot AND it was raining. i went down to the pool area, got changed, wet my hair, put on my rubber cap but when i went to open the final door to the pool, it was locked. what in the world? i went in my bathing attire to the front desk to inquire and they said something was wrong with the pool and that's why it was closed. couldn't they have posted a sign or something?

anyway. i ended up running 2.5 miles to my boyfriend's apartment later that day. i made him carry all my stuff on the transit LOL but i was really itching for activity.

last night i went for a run but it was terrible. it was 5 miles but i started to experience some serious bum pain (sciatic nerve) about 1/2 way through. i kept going because i still was halfway from home and by mile 3.5 i was wincing, had to stop and stretch, walk for a long period and was in serious pain. when i arrived home i stretched a lot and took a hot bath but i was still hobbling around and in serious pain. obviously i am really upset about this. i haven't been pushing it too much, i haven't been running on consecutive days so what gives? why does my bum hate me? WHHHHHHHHYYYYYYYYYYYYY?

so the pool is closed and i can't run.

the good news is that i'm leaving on friday for vacation. can anyone recommend some exercises that don't involve running and swimming (that's what i do) or anything else that would aggravate my bum pain? ones that make my stomach look flat and toned are key ;)
