Hills: Sit or Stand?

by Joe Friel

I was asked in a tweet last week if a rider should sit or stand when climbing a hill on a bike. I wish I could give a one-word answer, but that isn’t possible. As I’ve said so many times here in responding to reader questions, my answer must often start with “it depends.” This one is no difference. Here’s what this answer depends on…

Steepness. Low gradient hills are usually done seated. Steep hills often demand at least some standing. And the steeper the hill is, the more likely you are to stand up. When standing on a steep hill your body weight takes some of load off of the leg muscles. On the other hand, it tends to stress the aerobic system more. As a result you’ll probably breathe harder and have a higher heart rate when standing. But the steeper the hill is the less difference there will be when it comes to muscular- (seated) vs aerobic- (standing) system stress.

Hill length. The shorter the hill, the more advantage you will have by getting out of the saddle. You’ll create more power (again, because of adding body weight to the pedals) and get over it quicker.

Type of event. On low-gradient hills a triathlete or time trialist is less likely to get out of the saddle than a road racer. This is primarily due to the variably paced nature of road racing (as opposed to the steady-state riding of triathletes and TTers). If another member of the group is accelerating up the hill, you are often forced to accelerate to keep pace, or risk being dropped. A quick acceleration on a hill usually requires standing.

Body mass. The lower your body mass the more advantageous it is to stand on a climb. The greater your mass the better off you’ll be staying seated. One quick and simple way to come up with your body mass is to divide your weight in pounds (1kg = 2.2lbs) by your height in inches (1cm = 0.4in). So if you weigh 154 pounds (70kg) and you are 72 inches (180cm) tall your “mass” is 2.13 (154 / 72 = 2.13). I’ve found that for males the best climbers are at less than 2.0. These folks should stand a lot (think of Marco Pantani). Men in the range of 2.0 to 2.3 tend to alternate between standing and sitting a lot (for example, Lance Armstrong). Those men at 2.3 to 2.5 are best advised to sit a lot (like Miguel Indurain). Folks over 2.5 usually avoid hills. Women should use a scale which is about 0.2 lbs/in less (for example, under 1.8 are climbers).

So losing (or gaining) weight may change how you climb – and how well you climb. For example, a 1kg (2.2 lbs) loss of weight (bike and/or body) allows you to climb a 1000m hill with a 10% grade about 3.5 sec faster than when heavier at the same power output. Another way of looking at this is that 1kg is about 3w on a climb (so 1lb is roughly 1.5w).

Speed. At about 12mph (20kph) or faster staying seated and in an aero position if in a time trial or triathlon is usually a good idea. If your speed is less than 12mph then sitting up or standing is often better. This is affected, however, by the wind. A headwind essentially reduces your actual speed. So even if your speedometer says you are at 15mph (25kph) but there is a strong headwind then you are better off seated and even aero. While you may be more powerful above 12mph bike-wind speed when sitting up, your speed return on energy investment is not favorable due to headwind drag.

Fatigue. On long climbs, especially those late in the race, there may be some advantage to alternating standing and sitting to relieve muscle fatigue. Even if all of the other considerations listed here indicate you should stay seated, but the muscles you use to drive the pedals when seated are wasted, you may need to stand simply to give them a break.

Gearing. This is related to steepness. If you are on a hill but your gearing is so high that cadence bogs down you will need to stand in order to keep the gears ticking over.

Mountain bike. Standing causes the back wheel to lose traction when riding off-road on a steep hill on loose gravel or wet roots. So staying in the saddle is recommended for such climbs on a mountain bike. Pedaling while seated produces more even tension on the chain throughout the stroke and helps to prevent wheel slippage.

The good news here is that you can basically trust your instincts on hills in races. In most of the above situations your body will tell you when you need to stand or sit. It’s really not a great mystery – unless you overthink it. In this case, experience is the best teacher.

Training should involve both sitting and standing. Sitting will help to build greater muscular force for riding on flat terrain. It’s a bit like doing squats. Standing may boost your aerobic capacity, especially when the hill takes only two to three minutes to climb.

Basic Skills for Group Riding

By Gale Bernhardt
You don't have to be a competitive cyclist to enjoy the benefits of group rides. Utilized correctly, regular group sessions can motivate you, improve your fitness and make any ride more enjoyable. However, if you lack the technique or the fitness to ride with a group, the experience can be frustrating and leave you riding alone. In a worst case scenario, lack of skills causes you to crash, perhaps taking others down with you.

To help you get started, let's look at a few group ride basics.

Finding a group for you

When you search for a group to ride with, find out their general policies. Some meet for "no-drop" rides. This means that no rider is left behind and you can count on an experienced rider to stay with you. Inquire if someone in the organization teaches group riding etiquette.

Another option is to join a drop-in ride. These often begin in the parking lot of a local bike shop, with the pace of the group determined by the individuals or specific goals of the ride. Often, there are designated A, B and C groups to accommodate differences in riding speed.

The third most common choice is a race thinly disguised as a group ride. These are usually the fastest and most aggressive rides available. These rides are for very experienced cyclists and carry catchy names like, "Everyone Gets Dropped", "Ride Till You Puke" and "Wednesday World Championships." You have been officially forewarned just by reading the title.

Your local bike shop is a good place to start if you're looking for a group ride in your area. Most are associated with a club, bike shop or racing team.

Basic skills

A few basic skills are needed in order to successfully ride with any group. You must be capable of riding a straight line, controlling your speed, anticipating possible problems and watching the road ahead of you. At the same time, be alert for activity in your peripheral vision.

Hold your line -- If you have watched a professional cycling race, you know that every rider needs to "hold a line." This means that cyclists need to be capable of riding a line parallel with the edge of the road.

Practice this skill by riding 12 to 24 inches to the right of the white shoulder line while trying to keep parallel with that line.

The slipstream -- Some group rides practice staying together as one large mass—more or less—with little movement among the group.

Other group rides incorporate pace lines—or some version thereof—into their sessions. In its most basic form, a pace line occurs when one rider pulls a line of other riders behind them. Each person follows the rider in front of them by staying within a few inches to a few feet of their leader's rear wheel. This area of least wind resistance is known as a slipstream.

Staying in the lead rider's slipstream is called drafting. Riders that are in the draft position save upwards of 30 percent of energy compared to the lead rider. If you've ever had a chance to draft, you know that riding 20 miles per hour is significantly easier when you're following rather than leading. The difference is even more pronounced in a head wind.

Control your speed -- The lead rider in a pace line can stay at the front for just a few seconds or for several minutes. When you join a group that is rotating the lead position and it is time for you to lead, resist pouring on the gas to show everyone how strong you are. A pace line is happiest when the pace is steady. Fast accelerations or jerky braking motions disrupt the line and can cause a crash.

Keep eyes and ears open -- The first person in the group can see clear road. Thus, they need to point out road hazards—as do the rest of the people in the line. Pointing out hazards and verbal communication skills are important. For this reason, do not use headphones in a group riding situation.

When you are following someone, avoid getting a visual fixation on their rear wheel. Look several feet ahead, keeping the distance between your front wheel and the rider ahead of you in your peripheral vision. Watch for road hazards as well as motion to either side of the pace line.

Listen for cars approaching from the rear. A rear view mirror mounted on your helmet or glasses can be very helpful when watching for cars.

Maintain the pedaling motion of the other riders in your peripheral vision. Watch for sudden changes in cadence—this usually signals some sort of problem.

Anticipate problems -- If you are riding in windy conditions or it is a hilly course, anticipate changes in the group or peloton. When the peloton changes directions, sometimes the weaker riders are no longer sheltered from the wind and they fall off the pace. The same is true for a hilly course. Riders that can usually stay with the group on flat roads can fall off the pace on a hill.

Get accustomed to watching for signs that a rider is struggling. This includes having difficulty finding the right gear, breathing like a steam engine or constantly looking over their shoulder.

You don't want to be stuck behind a struggling rider if you are feeling strong. Pay attention to the signals so you can maneuver yourself into a good position.

Practice

This column just scratched the surface of group riding skills. Once you master the basics, you should continue to hone your skills. A good resource on mass riding is Racing Tactics for Cyclists by Thomas Prehn, even if you are not a competitive cyclist. Remember: in group rides smart riders often have the advantage over strong riders.

What to Wear for Runners

This is kind of neat. Runner's World online has a tool where you can enter in the temperature, wind, conditions and how warm/cool you like to be when running, and they make clothing and accessories recommendations.

Triglets, Part 1

Joanna Zieger's blog, Fast at Fourty, is always entertaining. Here is her latest post...

Do you remember Sniglets? They are words that don’t appear in the dictionary but should. Sniglets originated in the 80’s with the HBO series Not Necessarily the News. Triathlon has its own vernacular with words like “bricks” and “bonking” being tossed around, Triglets. I have come up with some of my own Triglets.

Aquarash – The strange burn that appears on the neck after a wetsuit swim.

Bodyslam – The full body muscle soreness the day after a race.

Bottle Shock – When you reach behind to grab a bottle from your back cage and it is gone. You realize it probably popped out 3 miles back when you rode over the nasty train tracks.

Cycleroma – The smell of a room after an indoor bike workout. The smell is exponential to the number of people in the room.

Fungoo – The residue on your bike frame from gels and drinks

Gasplorch – What to say to the race official (in lieu of the regular expletives) who pulled you over for littering when your bottle escaped on those train tracks.

Ill Suiter— An individual who wears their wetsuit backwards or inside out (yes, I have seen both).

Invisibuoy – The disappearance of the huge orange or yellow buoy on the swim if it is rough or if the sun is in your eyes.

Overage – Adding a few miles to your run or bike ride beyond what you had planned on your schedule.

Overstride – What happens when you are fading during a race and then drink a cup of cola.

Runnerstummy – GI distress that occurs during long runs, speed sessions or races that forces you to stop.

Spreader – An individual who takes up too much space in transition and encroaches on your area.

Tridew – The clammy, awful state that your gear is in when you have to pack it wet after a race.

Yo-yoer – A person who passes and drops back and repasses and drops back and passes again during training or a race.

Motivational Story

I love this story, told by a LUNA Chix leader...

The Luna Chix mission - to inspire women to “Get out and Play!” was embodied by Linda, an elderly woman in her eighties who I met during a swim. Linda slowly shuffled past me in the locker room - she was hunched over and had a sizable swollen mass in her right ankle. My initial reaction was to feel sorry for her. As she walked passed me I wished her a good morning which she took as an opportunity to start a conversation. I learned that she was a former model but was hit by a motor cycle nearly fifty years ago – ending her modeling career. After several surgeries, the doctors informed her that she would spend the rest of her life in a wheel chair. But she was adamant that she would walk, and with great determination she did. She told me she was an avid swimmer before the accident and has continued to swim nearly every day since. She wanted me to know that she was certain that she was walking today, despite what the doctors said, because she was physically fit before and after the accident. I no longer felt pity for this woman – I was inspired by her.
