Yesterday I did my first marathon. Running coaches probably don’t want to hear this, but I decided about 7 weeks ago that I wanted to try the Miami Marathon since it was close to home. Prior to that, I’d been running about 1 day a week, usually 8-12 miles, and I’d been doing other cross training, but I haven’t considered myself a “runner” for probably a decade. In fact, until about 6 months ago, I had probably only ran 5-10 times in the past 5 years. The orthopedic surgeon who replaced the ACL in my right knee said he found significant (3 on a scale of 1-4) arthritis and recommended against running. But I haven’t had any knee pain since the surgery, so I tried some shorter runs, then longer, and I haven’t had any arthritis pain, plus I’d read a few articles recently that suggest that running can actually help restore knee cartilage, so I thought I’d test it out…
I also just made a MAJOR change in my training regimen about a month ago. For years I had been training hard, and thinking that because I could maintain a high heart rate for long periods of time I was somehow “tougher”. I was working on the “No pain no gain” theory, like we’ve always heard right? Then I read Dr. Phil Maffetone’s books on heart rate training and found out I am an idiot, no surprise to many of you, but I’m a little slow. Dr. Maffetone recommends that you should spend most of your time training at a much lower heart rate (roughly 180-age, with a few modifiers). By his recommendation, I should have been training at between 136 and 141 beats per minute (BPM). I would routinely train for 3 hours and average 167! His theory is that training at high heart rates is very stressful on the body, causing the body to produce more insulin, weight gain (not loss) as well as other problems (insomnia, injuries, and actually reduced levels of athletic performance, not higher). I was seeing all of those problems.
So I started training at a much lower intensity level just before the new year, and I’ve started to see progress. At first, I couldn’t believe how S…L…O…W I was at the required heart rate. An old guy passed me on the track…Walking…Seriously. But thankfully Dr. Maffetone warns you to expect that at first, and that you need the discipline to stick with it until you start to see progress. Over the first month, he says, your muscle fibers start to adapt to be more efficient at the same heart rate, as you become more aerobically fit. I think I’ve started to see the results, certainly I’m sleeping better and my 1-mile split times at 139 BPM average have improved by about 25%. Still a long way to go though, but I think it will take a while to recover from all the years of punishing my body with constant high intensity training. I’m committed to sticking it out for a few months to see how it goes and will try to update again.
Back to the race. Perfect weather, great course, well organized. And the best part was my wife Maribel surprised me the night before when my two nieces (Tatiana and Gabriella) showed up and they all came down to cheer me on! My plan was to run the first 13.1 miles at a very low heart rate (under 141), then gradually bump up to 155 by the last mile, but still pretty low. I figured I’d finish right at 5:30 minutes, with a stretch goal of 5:00, but if I could run the whole thing I’d be happy. For reference, the cutoff time was 6:00, so 5:30 is at the far end of slow.
The race was sold out, with 25,000 participants (about 5,000 full and 20,000 half), and it took me over 20 minutes after the starting gun to get from the starting corral to the start line. The first 13.1 was a lot of dodging people on the crowded streets, but I felt great hitting the 13.1 mark at 2:30 flat, a little over my target heart rates but not too bad, and I barely felt tired at all. I started dialing back a little over the next 5 miles to make sure I had something in reserve for later, and paused frequently to stay fueled and hydrated at the aid stations. I never really felt like walking, and was never even close to “hitting the wall”, something I’m super happy about.
At about mile 23, I was feeling really good, so I started to dial up the pace a little. While my overall time was still really slow, I did the last 3 miles faster than the first 3, and I’m a day later I’m not too sore. I stuck to the plan, hit the target time exactly, finished strong, and wasn’t wrecked, so overall I’m pretty happy about the whole thing. And having Maribel, Samuel, Tati and Gabriella there was great – Tati and Gabriella jumped the fence and ran the last .2 with me and crossed the finish on either side, pretty cool of them.
I’m excited to see how this Maffetone training method works over the next few months. I’m going to look for another marathon to try later in the year, maybe late summer, and see how I compare then. Maybe I can finish above the bottom 15% next time 🙂
