a.k.a.: water intoxication or water poisoningRef: http://en.wikipedia.org/wiki/Water_intoxicationMarcy had asked a while back if I weigh myself before and after every run or ride. The truth is that I do try to, mostly because I have become concerned with my fluid weight loss and staying hydrated. And with that, hydrated properly without the risk of killing myself. Seriously! It's common for me to experience a net loss of about 5-6 lbs of fluid (considering approx 3 lbs of fluids consumed during ride) or 3-5 lbs during a 4-6 mile run in the heat (with no intake), or more with a longer run of 10-13 miles. So the immediate reaction is to just blast down a bunch of water, right? Well, we have to ensure the electrolytes are being replenished; they help balance fluid retention, cooling abilities of the body, and maintain proper muscle function. There is a very real and serious danger by either not replenishing them, or drinking so much water that you are essentially displacing the vital electrolytes in your system. As you all know, your heart is a muscle. The fibers are much more refined than skeletal muscles, however: they are smooth muscles that have an incredible amount of endurance for their density and weight. But if you rob them of what it takes to balance function, problems can arise. Please educate yourselves on this nutrition phenomenon, and hydrate appropriately. Steady water intake over long periods (vice blasting down a couple of gallons within a few hours of exercise) along with periodic moderate dose electrolyte replenishment (more so after long and/or particularly sweaty exercise) is what I would recommend to everyone as a base plan. Know your body, know the signs, and know when to stop.
So, other than that, I've been going at a pretty decent pace with the training. Last Thursday I essentially had 4 separate rides: a brick at lunch of 14.25 miles followed by a 2.4 mile run, a ride to the tri clinic of about 9 miles, 11 miles of sprint and coast with the tri clinic "students" trying to assist as many riders as possible and guide traffic, and then about 9 miles home. I was beat! Next day was a difficult 1500yd swim. By the time Saturday came around, I was happy that the group ride fizzled out due to rain: only about 5.25 miles and a lazy day.
Feeling lazy and inspired by the multitudes of people out riding and running (including Mendy's brother and his friend), I decided Sunday was a great day for hill repeats on the bike. I doubt I could have picked a more muggy day, however, especially as the sun came out and liberated all the recent rain from the grass and roads. I did okay, and knocked out 5 sprint repeats up a really steep and hateful climb, and then 2 more up a longer, more steady climb. Could/should have done more, but wanted to get back in case Mendy wanted to do something.
Yesterday was a "rest" day, mainly because Grace was out sick (congestion and boogers), so I couldn't really do anything during the day. After Mendy got home a nice thunderstorm decided to come out and play. Oh well, I guess there's nothing to do but go to Moretti's and get an Italian Flag pizza. Delicious! The guilt from that meal inspired me to do a quick 2.4 mile run at lunch (way off PR, BTW) and the Tuesday night group ride with the local tri/bike shop. We hammered pretty good for most of it, but also had to stop or ride slow many times for people to catch up. Still, a solid 31.5 miles with a lot of sprints, hills, and high speed pace.
I have been needing some bike work of late, so I'm glad to have ramped that up. I am feeling the need for running speedwork and long runs, however. I think about the G-man's pace for long runs and I wonder how it's humanly possible. He has reported holding a ~6:30/mile pace for 13 miles. One day, maybe, I'll be there too. At least I'm not too far off his swim times! :-) By the way, Chris, thanks for the props on your site!
Well folks, that's the high-level view of the last week. I honestly hope that, if you read anything, read and research the hyponatremia information. Especially you freaks living really close to the sun out in Arizona.
