Présentation de l'éditeur

Triathlon is among the world’s most gear-intensive sports. The gear you select and how you use it can mean big results—or bigger disappointment.

FASTER takes a scientific look at triathlon to see what truly makes you faster—and busts the myths and doublespeak that waste your money and race times. In this fascinating exploration of the forces at play in the swim-bike-run sport, astronautical engineer and triathlete Jim Gourley shows where to find free speed, speed on a budget, and the gear upgrades that are worth it.

FASTER offers specific, science-based guidance on the fastest techniques and the most effective gear, answering questions like:

  • Which wetsuit is best for me?
  • What’s the best way to draft a swimmer?
  • Should I buy a lighter bike?
  • Deep dish or disc wheels?
  • Are lighter shoes faster?
  • Who’s right about running technique?

Gourley reviews published studies in peer-reviewed journals to show what scientists have learned about swim drafting, pacing the bike leg, race strategy for short and long-course racing, and the fastest ways to handle transitions.

FASTER will change how you think about your body, your gear, and the world around you. With science on your side, you'll make the smart calls that will make you a better, faster triathlete.

5.0 étoiles sur 5 Great book of common sense for Triathletes 24 février 2014
Par cvu777 - Publié sur Amazon.com
Format:Format Kindle|Achat vérifié
I used all of the author's recommendations for my 2014 Eagleman 70.3 Ironman race. I have updated my review since each theory was tested. I hope this update helps you to race faster and save money. The author provides lots of physics and explanations on Force, Momentum, Acceleration, Drag, Gravity, Yaw, Aerodynamics and Wind Tunnel testing. His theories are so practical they border on common sense. Here's the summary of this great book: 1) Lose weight! Don't buy a Cervelo P5 when the difference between the P2 is about 3lbs. Save the money and go to Jenny Craig and lose 15 to 20lbs. Losing weight will keep you from getting Plantar Facsciitis. It will make you more efficient in the pool. You will feel great on the run & on the bike. It will also keep you from overheating as fast as fat athletes. Force = mass x acceleration. If you lose mass (15 to 20 lbs), and your force is the same, you will have faster acceleration. After I lost 25 pounds over two years, my run speed increased from a 12 minute per mile to a 10 minute per mile. I feel so much better without the extra weight. 2) Buy tires with low rolling resistance. My continental gatorskins have 2x the rolling resistance of the Continental GP 4000s. I purchased the GP 4000s and I currently use my old tires on my bike trainer. 3) Work on your swim and run techniques. Go to a Masters Program and a good running program i.e. http://www.goodformrunning.com/. Training with a Masters and running group really helped me when I did not feel like working out. 4) Buy a Power Meter. After my 70.3, I purchased a Stages Power meter and I highly recommend this purchase. The power meter measures your power and cadence. Its unfortunate that I'm only able to generate only 130W on my rides. I hope to get it to 175 to 200 Watts in 6 months when I race in the 2015 Eagleman 70.3 in Salisbury, MD. 5) Rent your Zipp Wheels; don't buy them unless your power meter is 250 Watts or above and you completed Step 1. For $180, I did rent Zipp Firecrest 404 wheels for my 2014 Eagleman 70.3 and was 1.5 mph faster. Honestly, I cannot justify paying over $2000 for a set of zipps. I'll probably rent a set of Firecrest 808 wheels for the 2015 Eagleman. 6) Get a proper bike fit - The Retul method is pricey but better than FIST fittings. I went and paid $$ to get this done. It was worth the money. I also purchased an ISM Adamo saddle to make my rides more comfortable. His other tips are great so buy this book.

Any triathlete or anyone thinking of becoming a triathlete has heard the phrase, " if you want to go faster, open your wallet." Its a matter of fact that to be the fastest athlete, you have to have to best gear, the latest and the greatest equipment, the most aero bicycle, the lightest components, the newest running shoes and be sporting the latest and greatest trends. Right?

Well, maybe not. Jim Gourley, in his new book Faster, uses science to demystify many of these long held beliefs. It's no wonder triathletes (and I am one myself) are such easy targets for the marketing genius' who peddle their wares--we are suckers. We flock to companies that promise to shave a minute or two off our time, or guarantee a faster recovery all for some inflated price tag. Triathletes can't seem to buy these products fast enough. But, do we even know what we are buying and what these products REALLY do? A marketing promise after all is something that should be taken with a grain of salt.

In his new book, Faster, Jim Gourley, attempts to demystify these promises and guarantees. These common traps triathletes so readily fall for simply to be a little bit "Faster."

Read this book, save yourself some time and a whole lot of money. Gourley uses sound science and proven facts to show what works and what doesn't. Where to spend those hard earned dollars and when to keep them in your wallet. Before you hit your local triathlon shop, where they are hoping you can't wait to shell out big dollars on a P5, some Zipp 808 race wheels and all the goodies to go all with it, do yourself, and your retirement account a favor and spend a couple of days and reading this book.

5.0 étoiles sur 5 Readable, smart discussion of bike, run and tri science. 25 septembre 2013
Par Michael B. Gore - Publié sur Amazon.com
Format:Broché
I've read a lot - A LOT - about the science of bikes and running. Which handlebar is lighter? Should I get Zipps or Reynolds? What about tire width??

This book breaks it down into readable, smart graphics and writing about the WHY behind component design as well as techniques. Want to run faster? There's physics about stride length that's relatable. Want to ride faster? Learn about if having an aerodynamic or light bike is more important, and how fast you have to ride for any of it to matter. It's a great gift for any of those nerdy friends you have who crinkle their numbers before races or babble on at dinner about their new minimalist shoes. If you're one of those people, this could save you a lot of time and money, and provide you with some cold, hard science the next time you smackdown on the group ride.

3.0 étoiles sur 5 Good book with some errors 6 octobre 2013
Par Michael A. Marsh - Publié sur Amazon.com

In essence Faster is physics primer with practical rules of thumb. There is a lot to like about this book and I recommend its purchase.
Problems I find with the book:
Chapter 2, deals with swimming, has factual and conceptual errors as well as concepts not developed. It is stated, "the amount of water the object displaces is equal to its volume." This a partial statement of Archimedes principle which is true for a completely submerged object but not one partially submerged, such as a typical human. On the average specific gravity of a human is slightly less than the specific gravity of fresh water at usual swimming temperatures. Meaning 99% of humans will not sink in fresh water unless they are extremely lean. In general the buoyant force exceeds the weight of most humans. Fat floats. So the main thrust of this section, " that the force of water pushing on you as you swim is dependent on your volume not your weight", is false. In addition on pg 36 it is stated a neoprene wetsuit "displaces a large volume (and therefore mass) of water in comparison to its own mass". This statement is completely false. Neoprene will displace exactly the weight of water equal to its' own weight.
Neither chapters 1 nor 2 ever develop the concepts of center of gravity nor center of buoyancy. Kind of weird given this book is primarily a physics of triathlon book.

Chapter 4 is The Bike: Weight & Aerodynamics. Overall it is a very good chapter but again a factual error. On page 97 there is a reproduction of a table which references a paper, however upon reading that paper the table is incorrect as well the conclusion. Specifically, the table in the chapter are the probability of yaw wind angles for a car traveling 55 MPH not 30 MPH the table is purported to reference . It is stated in the chapter "The most likely yaw crosswind angles is less than 10 degrees". This is true for a car going 55 MPH with mean wind speed of 3 meters per second, however not true for a car traveling 30 MPH where yaw angles greater than 10 degrees will occur 28% of the time and greater than 15 degrees 12% of the time. With a bike going 25 MPH or 20 MPH or 15 MPH, which would be typical bike speeds (average from IronMan speeds range from 14 to 23.5 MPH), the typical wind yaw angles would be larger. Also higher average wind speeds will increase probable wind yaw angles. Reading this page would make me ignore yaw angles greater than 10 degrees when comparing products, however the study referenced contradicts this, as I believe, does bike industry data.

I liked the book and do recommend it. The 3 stars and criticism are to improve the next edition, which I also will buy.
