  1. Yup, he's not quite at his peak at the moment.
  2. Okay, here's a little exercise for you. Take the avg power in his attack, divide by 63kg (to be on the safe side). Then multiply by your own weight. Now, try do that power for 4 minutes, then immediately do 1 hour at 0.9 intensity factor (90% of your FTP) That's what it takes to solo win a race like that!!

  5. Nope' date=' Austin is 100% right re Worlds View. I received notification from Alec Lenferna today as it was one of the proposed events for proposed SuperSeries. Austin also correct about a few other things [/quote'] At least you are going to be seeing more of a certain individuals SRM files because of a team relationship you have and his plan to move... I am really excited about that! World class! Too strong for road racing in this country!

  7. The problem is actually not well enough defined for any answer to be deemed correct. Does the vehicle continue at the same speed, or does it slow? This changes the situation significantly, and from JB's perspective he would not have been able to tell whether the wheel accelerated or the vehicle decelerated, as both would appear the same from his point of view. If you make the following assumptions: - Vehicle continues at same speed. - Wheel accelerates i.e. gains speed when it detaches. Then it is clear that the balance of forces changes resulting in a nett forward force causing acceleration. Assuming that rolling resistance decreases, this does not account for a nett positive force, it only accounts to a decrease in negative force (positive force being in the direction of motion, negative opposing motion). Something must still be pushing the wheel forward. Since the wheel is detached, the only possible source of this forward force is inertia, which we know the wheel has due to it's forward motion, and it's rotation. As for the rotational energy of the wheel, the truck puts energy into the wheel when the wheel get's accelerated, and the wheel puts energy back into the truck when it decelerates.
  8. Sorry, my bad, energy stored in the wheel is a sum of the 2 types of kinetic energy rotational = (1/2 x I x w^2) plus forward motion = (1/2 x m x v^2) I used the term potential energy because I was talking about stored energy. That stored energy must be released, and when the wheel is set free, it is released into rolling and wind resistance. bruce2008-11-13 04:55:23
  9. I would suggest that the balance of forces changes significantly. The inertia of the wheel is far greater than the rolling and wind resistance it encounters when it releases - given a force imbalance, the wheel will accelerate initially, until the balance of forces is restored. The truck either continues as it was, or actually decelerates if the wheel that has been released is one of the drive wheels.

  11. In the Chris Carmichael article, he gave a figure of just below 400w for LA's current FTP. I think 20% is too much for the draft advantage for 2 reasons: 1. LA is quite a bit smaller than this John dude, WKO+ file has John at 86kg. 2. LA in an aero position is not going to be providing much shelter to the guy behind him. So, maybe 10% to 15%, which correlates well with the Chris Carmichael article. Would guesstimate LA's weight to be around 75kg at the moment.

  13. This is a very SICK kind of humor!! Heard the dude left a wife and 2 kids behind and it wasn't a newby! Luckily he didn't hit any innocent people... I had a supermotard for a few years - even with such a 'slow' machine (165 km/h max) it wasn't easy to control myself now and then - loved the 'kicks' too much! Just stick a photo of your family on your petrol tank or something... behave yourself out there Nice bike btw! Yup, he was a 37yo doctor, and his wife was a doctor as well, couple of kids IIRC - very sad! There was a long discussion on Think Bike forums about this incident. I also got there just after it happened.bruce2008-11-03 23:15:37
  14. Protein does lower the GI, but protein stimulates the production of insulin. Insulin is critical in the conversion of carbohydrates into glycogen so stimulating insulin production reduces the time it takes for the carbs you ingest to become available to muscles as fuel. Also, even when glycogen is not depleted, the body still gets around 10% - 15% of it's fuel from protein (i.e muscle tissue) through muscle catabolism - having some protein (in the form of amino acids) in the bloodstream can reduce the damage to muscle tissue through muscle catabolism. As far as I know, Energy Dynamics was the only gel that contained some protein. The protein/carb ratio is important because it affects the speed at which the carbohydrate is absorbed through the stomach walls.
  15. I sense some Vernon Koekemoer/Chuck Norris type quotes brewing here
  16. They look a little bit like TABATA but with longer recovery periods. I personally believe this is a little early for these types of intervals - I would generally prescribe them 6-8weeks before main target event. http://www.experiencelifemag.com/issues/march-2008/fit-body/the-tabata-tune-up.html
  17. Oops, sorry about the double post, but in my defence - I wouldn't have seen it in the "International Events" forum.
  18. I was sent this article via email, I'm not sure of the source: When Lance decided to return to professional cycling, he could not simultaneously flip a switch and erase all plans he had made for the late summer and fall. There were meetings and events on his schedule that had been planned months in advance, and he wasn?t going to back out of them simply because he?d decided to race his bicycle again. This made his training schedule for October more of a challenge than usual, but he still managed to get on the bike for 20-24 hours a week throughout this month. Here?s a look at an outline of his training plan for the month: Lance?s Training Outline for October 2008 2 x per week 5-5.5 hrs endurance pace 2 x per week 3-4 hrs endurance pace with 2 x 20minutes at just below LT pace (380-400watts) 1 x per week Tuesday-nighter 1 x per week 3-4 hrs with 2 sets of 4 x 20seconds max effort x 40 seconds recovery 1 x per week day off-travel, rest. Overall his training is progressing quite well. His performance during his longest endurance rides has stayed pretty consistent over the past few weeks, but these rides are taking less and less out of him. That indicates he?s adapting to the increased training volume and it?s time to incorporate more intensity. He?s been doing relatively long intervals just below his estimated lactate threshold power to start building his sustainable power at threshold, and some efforts above threshold to bring up his power at VO2 max. I say ?estimated lactate threshold power? because we haven?t gotten him into the lab yet, but with 15 years of data and Lance?s knowledge of his own performance, our estimates are typically within 10 watts of his actual LT power. In addition to putting in the miles and starting on some structured intervals, Lance spent some time out on the road with aerodynamics guru Steve Hed. After more than three years off a time trial bike, we didn?t want to just throw Lance back into the same time trial position he used in 2005. Although we?re not starting from scratch, the time off actually allows for greater opportunities to make significant changes to his TT position. The time with Steve was quite successful and we expect to see very good (meaning low) drag numbers when we go to the wind tunnel on Monday, November 3. The next day we?ll test any tweaks we make to his position using a power meter in real-world conditions to confirm that changes made in the wind tunnel actually make him faster on the road. I would guess LA's weight is around 75kg at this stage. He was down at 72kg's when racing TdF'sbruce2008-10-30 02:01:28

  20. I asked him during the race if he knew a good bike shop that sold cycling shoes Both David and Johan are absolute gentleman - both will race themselves into the ground but never let the competition go overboard.
