De-slacking in progress
started running @ age 48 [lost 70#+, quit a 30 year pack/day habit>> ran HM] Ran a few years then quit. Gained 70#+ back and smoking like before. Time to get healthy again @ 52 years over with the C25K program and beyond again. RE-start date 1-13-14
Unless you are on a low carb diet you had 1500-2000 calories worth of glycogen stored in your muscles. That is enough for many hours worth of running before glycogen depletion becomes an issue. There is no way you burned it all in an 8 mile run. It sounds more like dehydration or maybe something out of whack with your blood sugar. Have you had it checked lately? Tom

Turn off your mind, relax, and float downstream...
maybe not the blood sugar levels, but definitely the heart rate! Supraventricular tachycardia (SVT) is a HR approaching 200 bpm - (Tachycardia is a response to the body's need for increased oxygen delivery due to some stressor on the body, like running 8:30 min miles that you aren't used to for an extended period of time.) It will usually resolve itself once the stressor ceases. But still - that's dangerous territory, so slow down!!
SVT can actually run your heart rate much higher. My son has this condition and was clocked at an astounding 260+. (completely off thread ... he's now on beta blockers and is active in soccer, basketball, swimming, etc. ... minor surgery expected to fix the problem in the next year or so when he's big enough)
Blaaahhhh
