By looking at it, and not inputting anything, I'm going to say, not very, and probably a complete waste of time. Get fit, train properly, ride your bike, learn to race if you want. I'm not sure why you're so fascinated on 'ideal race weights' and body composition etc... ??

I'm trying to lose weight at the moment and finding it hard as I am not fat anymore but that is not good enough for competitive cycling. I'm just trying to get opinions from more experienced riders. This is all very new to me as I have always been overweight in the past.

How accurate is the calculator for ideal racing weight?

Postby cyclotaur » Sat Jun 21, 2014 7:06 pm

I tried it and it told me I'm 5 kg over - which is exactly what I'd like to lose so it's ball-park accurate I reckon.

I'm not looking to race of course, just ride a bit better.

Have you entered a race yet?

Why don't you turn up and see how real people race rather than trying to compare with the genetic freaks who's full-time job is either racing a bike, or preparing to race a bike.

I worked out mine ideal racing weight is 68! I haven't weighed that since I finished my army recon course 15years ago.

I have raced when I was overweight. I am thinking of racing this summer season but want to be very ready this time (even if I am starting in D grade)!

So you're planning on racing D grade, but you feel the need to compare yourself to professionals.

You need to direct your energies elsewhere.

Even A grade club riders would be happy to climb like Cavendish or sprint like Contador.

I'm doing D grade to get experience and confidence. Ultimately, aim is to get into A grade.

What is your plan to lose this 5kg?

How long do you expect to lose it?

I plugged my numbers in and it gave me 69kg, which was my racing weight when I was rowing at elite level and is just under the weight I'm looking to hit this year, so for me it was fairly accurate (for reference I'm 189cm tall). I drop weight by eating less and moving more, I use a calorie tracker like MyFitnessPal and follow my training plan making sure I don't miss any sessions. Dropping 5kg will probably take somewhere between 6 and 12 weeks depending on how quickly I want to lose the weight.

Why are you trying to be heavier as a cyclist than as a rower?

Ha ! A plan would be a fine thing !

I tend to drop a couple over summer and put them back on over winter, so my weight swings between about 77-80kg. :/

I have a reasonable incentive to upend that pattern this year though, but not sure if it'll happen - I'll need to be a very disciplined eater over the next 2 months to get anywhere near 75 by September.

And I'm not that disciplined .... :)

It told me my idea weight was my current weight

As it doesn't ask you your height, is it saying that midgets and basketball players should be the same weight?

From the calculators information page.

To use this tool you need to know your current body weight and body fat percentage. The estimates generated by this calculator are based on realistically attainable body fat percentages for men and women of various ages as suggested by data collected by Kip Russo of Body Fat Test, Inc. using the hydrostatic weighing method. Therefore it is ideal—but not essential—that you have your body fat percentage determined by the same method.

There’s a reason this tool is called an “Estimator” rather than a “Calculator.” Optimal racing weight is influenced by too many factors to be predicted with a high degree of accuracy for all athletes with a simple formula. The only way to definitively determine your optimal racing weight is to actually attain it through proper diet and progressive training. So think of the Racing Weight Estimator simply as a way to establish provisional goals for your weight and body composition.

The information supplied by this tool should not be construed as medical advice.

I'm doing D grade to get experience and confidence. Ultimately, aim is to get into A grade.


Why do you feel the need to be at A grade level at your first race?

Sure have your goals to hit weight targets etc. but you will get to A grade much faster by starting racing next weekend, rather than holding off waiting for some magic number.

I'm surprised you haven't started a thread on power output. Being light alone doesn't win races.

Having good power/weight ratios doesn't necessarily win races unless you have A grade performance in a D grade race, in which case you won't learn anything from the experience.

Skills development, race tactics are all part of the package, because whatever aspect you choose to measure there will be someone with better numbers than you.

Enter some races, do badly and learn from the experience. You could even post your reports up and get some feedback.

If you truly get to A grade performance without even bunch riding experience, you will be a danger to yourself and others in a race where people will be relying on you to behave properly in a racing bunch, because they leave smaller margins for error.

Cameron

Half of B grade at my club would be classed 'overweight' when it comes to competitive cycling, including me. Maybe when you're up to doing a Grand Tour, you could worry about getting your exact ideal race weight worked out, but unless you're up to that, just go and race dude. Don't try and compare yourself to the pro's. By riding and racing you'll probably continue to lose weight, and if that's your goal then hoorah, you're half way there.

So you currently have very low body fat? How does it feel having such low body fat? Are you natural this way or strictly diet and exercise?

I won't be at A grade level in 3 months time (being at racing weight doesn't automatically mean A grade) but hopefully B grade (fitness but not skill) level (and that is why I am starting in D grade). Actually, I love to race and often try to race anyone that look fast every time I go out riding or commuting. However, I don't want to do it formally yet. I take formal racing very seriously and feel that physically and mentally I am not ready now. When I do enter into regular crits, it might turn out that I hate racing in a bunch in which case I will only enter in time trial races.

I actually have started a topic on power
viewtopic.php?f=43&t=75281

What I really want to achieve is a high 20 min watt/kg (purely for personal satisfaction).

Ha ha, I'm not trying to be heavier, I'm nearly 20 years older and figure if I can get within a kilo or two of the weight I was as a 20 year old I'll be doing pretty well :lol:

Crits are a bad way to get into bunch racing. You need to be good at riding in a bunch before you enter your first crit, particularly at Kew which whilst it only has one tight corner there is not a lot of room to recover from someone messing it up. Someone like Jules21 will have a better idea of how often that occurs but my experience there was that someone would touch a pedal on that corner at least once every race, although it didn't always send them off line. The fight for position going into that corner could be pretty intense too.

You would be much better prepared for that if you started racing now. Chasing randoms on the street for a couple of minutes is not racing, (unless you count Commuter Cup points). You can still work toward your weight and power goals but you need experience to go with it.

Cheers,

Cameron
