Congratulations to Ivan, Sand, and Mad Cow on their efforts today!!! Really great job to all of you. Following up on my crash & burn of a 10 miler on Thursday, I had a borderline disaster of a run this morning. Supposed to be 15 at 8:35s (I did it in 8:38s two weeks ago). Left the house at about 6am into mid-50s and a light on/off rain. Conditions were better than fine. After about 1.5 miles running in the (mostly) dark, I moved into a wooded part of the path I run and something started feeling very, very not right. I got sort of light headed and my vision was goofy: kindof dark at the edges and out of focus. I kept running thinking it would pass but it wasn't getting any better. At one point I even slapped myself a couple of times to get some adrenaline going and that didn't help. By mile 3 I started slowing down and became concerned that something serious was going on. On my long runs I carry my phone and started wondering how I would describe to the 911 operator where I was on the trail. Probably a bit of an over reaction, but at 6:30am on a lightly used bike trail in the woods... I got nervous enough that I stopped running. I walked for 5-6 minutes and started to feel normal again, so I started running again - I figured worst case I'd stop & walk, but I was several miles from home and didn't have a lot of choices. At 4 miles I still felt normal so I kept going - and actually turned in 8:33s from miles 4 - 9, including looping back to the house to get my second water bottle. But after that I couldn't maintain much speed and barely kept it under 9/mile, logging 8:55s from 9 - 14. At 14 I was spent. I ended up walking for a few minutes before jogging it in to complete 15. I can only figure I've hit a wall in my training and the fact that I never get enough sleep (as evidenced by the fact that I'm up now). After I got home and got out of my running stuff (it rained most of the run so I was soaked to the bone) I took an ice bath and a 2 hr nap. I'm going to try to force myself to get to sleep earlier this week before my 20 miler next Saturday (I'm going to do a fully supported run near my house, which will have about 500 runners). I'm not really sure what else to do.
