on Thurs 7/29 I played hooky from work and did Big Training Day with some friends in preparation for my first iron distance in september. It was going to be a test to see how I was preparing for the race by swimming 1 hour, riding 5 hours, then running 2 hours. I failed. the swim went fine. 3,000 yards in 1hour 1 minute with only some minor foot cramping. The ride was another story the first two hours was a walk in the park. Until I flatted no problem quick tire change minimal cursing and I was back at it. a quarter mile down the road I flatted again. We ride on. I'm a type 2 diabetic so I am consntantly drinking eating and checking my sugars. Around 3 hours my sugars a little high but not bad. I am more fatigued and sore. We keep riding. at a pit stop I check again and my sugars are more elevated-not dangerously so but defintiely heading in the wrong direction. I keep drinking but forgo any more gels. I am sweating like a pig and keep losing power. about 4hours in I have to stop on top of a hill. my sugars are in a 'not good but not dangerous' territory. I regroup and we ride on. 30 minutes later my friends notice I am swerving a bit on my bike and slurring my speech. they pull the plug on my ride. I pull out and hit the air conditioning and rehydrate while they ride on. I call home and freak my wife out by slurring my speech. I recheck my sugars and they are thru the roof. Not bad enough for ambulance ride but it is the highest reading I've had in years. I take more of my meds and after over an hour my sugars go to a safe level. At this point I run 20 minutes to burn off some anger. No Major issues besides a small headache at the beginning that wears off. I woke up the next day feeling relatively fresh and did a good 80 minute run saturday feeling great. So I am assuming that dehydration wasn't the problem but rather my sugars. My doctor is a marathoner and triathlete but have spent the last couple days playing phone tag with him. my initial response was that I was done w/ iron training but am now thinking that it may just be a matter of more testing my sugars and not being afraid of using my meds during the event. But till I have a talk w/ my doc and sitdown with my support crew I'm not sure where this season will be go.
