Intervals: Pain yes, but gain...


On the 51-mile out and back ride I do as a way to keep the belly fat in check, I have sections I ride through that the fitness gurus call “intervals.”
In a perfect world, intervals are sections of the ride to rip it up and pedal into a sprint to improve cardio and stamina. They’re the sections that mountain bikers get all the time when they have to hit the granny gear and pedal fast just to get up a steep section of trail. Road cyclists usually pace themselves on their climbs because, as is the case on mountain roads, they can go on for long, nasty stretches.
So on my interval sections, which vary in distance and are flat and variously sloped, I force myself to ride as fast as I can. This is a relative thing. The biggest obstacles to getting up to speed can be depleted energy from riding mucho miles, heavy legs from logging a lot of miles in consecutive days and headwinds or sidewinds.
These intervals help spark energy when I’m slowing down on my regular ride. But they pay off, and bring mental toughness and long-ride stamina. If you do a regular ride, throw some intervals into it. That is, if you like pain! But there is gain to be had.
Here’s a play-by-play of the ones I do. I figure it’s therapeutic to share my high-speed pain caves. Hope you can relate!

No. 1: This comes at the approach of a bridge about five miles into the ride. I usually have plenty of energy to tap into here. As I ride onto the upslope of the bridge I pedal hard, looking to hit 20 mph. Some days I do it without much problem. Other days it seems like I’m pedaling concrete blocks to hit that speed.

No. 2: This comes at the end of my first split, which is 14.5 miles of mainly flat riding, with a few hills and rollers thrown in. It’s about 100 yards. It starts with a sharp left, and then continues straight and flat to the end. I gear up to the highest gear on the approach, then stand on it to build cadence. This is usually not too tough because it’s such a short stretch. Thankfully, it’s over pretty fast.

No. 3: This is a flat half-mile stretch along a lake that comes after an easy climb along a bridge and a fast descent. And it’s almost always in a strong wind. I try to get to 20 mph as soon as I can on this stretch, but if there’s a headwind, and there often is, I usually don’t get going that fast until the end. It can be a serious slog to get up to speed. I do the same on the return. Love it when there’s a tailwind either way, since then, making 20 isn’t too tough at all. That’s how I get a quick read of a tailwind. If I’m suddenly flying along with the greatest of ease, I’m thinking, “Hey, my legs are strong! Oh wait…tailwind.”

No. 4: This is stretch is a bear. It comes after a fast descent and is a mile of absolutely flat riding, with cliffs on one side and a lake on the other. Here the wind is almost always in your face or at your back. So if you get a tough headwind going in, you get the tailwind coming back. The wind giveth, and the wind taketh away. But it’s always different. I try to stay as close to 20 mph or higher as I can, but with the mile length and headwind, before long it’s a grunt-fest. I usually start off at the 20-22 mph speed, then it becomes a challenge to see how long I can maintain it. I’ll shift down to keep the cadence high as I tire, but wow, it feels like someone slowly closing off your windpipe. And it finishes with a gradual climb, which is the very next, ugh, interval.

No. 5: In some ways this is the hardest interval of them all. It’s about 100 yards of upslope that isn’t steep, but after pedaling hard against the wind for a mile, sucking air and filling the legs with lactic acid, it’s waiting to finish you off. I shift down into high cadence as it starts to rise and let it rip, with the goal of hitting 19-20 mph. But, wow, that’s a tall order. Hitting 14 mph is hard enough, but to get up to 19 or 20 is a high plateau which I only hit when there’s a tailwind. Usually I get to 16 or 17, and am close to oxygen debt at the top. Ah, good times!

No. 6: This comes close to the finish of the first half of the ride, and is about 100 yards of very gradual climb. In a low gear it’s fairly easy to get up to 20-22 mph at the end of it, and continue on to more gradual climbing. I do it, because it’s a section where it’s easy to be lulled into a slowed down pace that bogs down the overall time.

No. 7: This is the last steep pitch, about 50 yards at the end of the first half, which is preceded by a long gradual climb over about three fourths of a mile. Here, I stand on it in the second lowest gear and try to power through. It’s a hard pull, since it comes after 25 miles of interval-laced riding. I don’t look at my speed, just try to make it with a strong cadence. Now, need food!

Heading back after a rest and food, it’s a lot of fast descending, with challenging return intervals on the Nos. 4 and 3 sections. I don’t do a reverse sprint on the No. 2 interval, which comes when I’m recovering from finishing a 9-mile, mostly downhill split. I try to get a strong approach to the bridge on the reverse of the No. 1 split, but at that point I’m usually sucking wind and grabbing for my water bottle. Any reasonable pace is what I’m trying for. If it’s 14 mph, I’m doing OK, still moving forward!

No. 8: The last 100 yards of the return 14.5 mile split is an all out grunt sprint, and I usually get to 20-22 mph there. After that, there’s an easy does it ride with heavy traffic for the final two miles home.
Ahh, didn’t that ride feel great?

Mountain biker’s revenge
 Let me just say that I used to ride on the nearby paved bike trail – which is best suited for road cyclists – on a mountain bike. So I was used to being passed by roadies all the time. So the other day, I’m trying to ride fast through a stiff headwind on a flat, and I’m working hard, all out. I suddenly hear a high-pitched whine that is a completely unfamiliar sound on this trail. Before I know it, a guy on a motorized mountain bike passes me. What?
This guy figured out a surefire way how not to be passed by roadies or anybody else on this trail. He just hits the gas, and can pass any roadie, even the dudes in the pro peloton. Just wish I had the steam to grab his rear wheel. Not a chance!

Thanks Tom
Tom, riding on a nice Felt bike, stopped to check if I was OK recently when my rear tire flatted. I had all I needed, including my hard won knowledge on how to put in a new tube without puncturing it. But Tom hung out and chatted as I got the tire back in shape. And hey, it was nice! Thanks Tom and to all the several other riders who offered help.

Til next time, remember to strap on a helmet every time you get on the bike. Then keep the rubber side down, ride safely and have a blast.
