Couple of things going on here.....Ran last night from the Trak Shak with my buddy KDS and it was hot! When I say 'hot' I mean HOT! I wilted like Chamberlain and I like the heat!!! We may have started a bit too fast (don't do as I do, do as I SAY do!), but we backed it down pretty quick. I still prefer warm weather over cold. Don't have to think about gloves, long sleeves, short sleeves, yada, yada. I know it's gonna be shorts, socks, jock let's go! However, I don't want to belittle the potential damage of running in the heat - either distance or being unprepared. I've known runners that have suffered from heat exhaustion (including yours truly at the Honolulu Marathon) and one in particular some years back that died - a tragic loss. We're smarter (cumulatively) now, so be careful out there. It is muy caliente and that will affect your performance, so lower your expectations, keep your aerobic base up and run for fun. It helps when you think that sweat is your fat cells crying and if you're like me those bad boys are bawling! I'm sweating like a hairy mule pulling a wagon; but in a perverse fashion....I like it! I always preach that running isn't for those with an 'instant gratification' mindset. It's not a microwave, drive through run a marathon, lose 10 pounds NOW kind of thing. However last night I was talking to one of my 'runners'; a guy who (by his own definition) is "overweight, out of shape, and trying to get back"(into shape). In fact, and I'm paraphrasing, he said that, 'when you've been on basically worthless for 30 years and have 3 stents, it's gonna take a while.' Good point! I'm proud of him for making the effort and he's really doing quite well. In 7 weeks he's gone from literally nothing to running 3 miles! He still runs out of gas around 2.5 miles, but he's doing great by almost any standards (take THAT Pearl Izumi and your idiotic ad campaign....we'll discuss later). My point is that in, let's say 15 weeks, he should be running 5 miles (actually more, it is 10K in 10 weeks, but let's tap the brakes) 4 to 5 days a week. He'll weigh less even without modifying his diet, be stronger, leaner and more confident. His heart will be stronger and his lung capacity greater. Will he be where he was 30 years ago? Maybe not exactly, but I'm going to say close. If he keeps it up to say 26 weeks, modifies his nutrition at all and keeps running he will not only be where he was 30 years ago, but BETTER! What's the old saying, "If a man learns nothing, changes nothing in his life from age 20 to 50, then he has only succeeded in wasting 30 years." Well in the Grand Scheme of Things 20 weeks +/- or minus is microwave/drive through/gotta have it now. It IS instant gratification! Think about that, it's 1/60th of the 30 years (give or take). Okay, it's still not a *poof* miracle, or 'blink of an eye'...but it's a s l o w *poof*. Maybe 2 blinks....30 years is a long time. If he keeps this up, maybe he just 'existed' these last 30 years; but he can truly be ALIVE for the REST of his years, in the Grand Scheme of Things.
