Torque seems to be fine. There are no points in the file when torque is non zero while cadence is zero. You can usually see the problem because the power never goes down to zero during periods when you aren't pedalling. The one thing you don't mention is that you have changed powertap units since you did your previous ftp test.

Does anyone know if there is a way to convert a gpx file that was constructed in MapSource using routing to one that does not need routing. I am busy mapping out the stages of the Ladies TdF next week. I have the European City Navigator maps which allow auto-routing. Now when I upload the gpx file to a website, the waypoints are quite far apart and the route does not follow the road.

Maybe rat's bums are a figment of your imagination, and duct tape too, oh, sorry, wrong thread

Dude, it's not that difficult, all I have to do is lose 10kg's and I'm sudenly a 6w/kg rider... The rest will follow... We are all 6 w/kg riders, it's just that some of us can do it for 30seconds and others can do it for an hour

ChrisH, your argument goes something along the lines "I cannot comprehend it, therefore it does not exist". So, every day when a discovery is made, deeper insights into the universe on a largest scale, and quantum mechanics on the smallest scale, the space-time continuum, all of these things that 100 years ago we did not even know existed - does this mean that these things only existed once we comprehended them? Stating that the existence of something is predicated by your comprehension of it, is with all due respect extremely arrogant.

I have no problem with "evidence based" philosophy. But, let's consider the evidence. Just the creation of a human being is a process that's complexity is far greater than humans (the supreme beings on our planet) can accomplish. We don't even fully understand the human body works, never mind being the creator of it. The planet earth is still not fully understood. The combination of elements at the core is just right to sustain life on the planet - surely something far greater than humans can accomplish. So, it is clear that humans are not the creator, so who is? There are two answers, either a random collection of elements came together to start the process, or there is an ultimate creator (or certainly an entity with far greater powers than humans). In my mind, to believe that all these things happened randomly, that the improvements in species through evolution is purely luck, requires a far greater leap of faith, than to believe there is a creator, that we don't yet understand. The Christians call that creator God. And assign other benevolent responsibilities to that creator - such as ensuring certain laws are in place so that we can try to live together, and giving meaning to our lives. After a lot of thought about this in my life, I've come to the conclusion that believing that there is no creator, is far less plausible, than believing there is. Debate will rage as to which god the creator actually is. But that is a different topic.

Andrew won by over 1 minute. Graeme looks a bit like Chuck Norris (or maybe Vernon Koekemoer) which makes Andrew's win all the more impressive

I personally think a lot can be done without too much effort. But these things are more overall cycling related, not event specific: - Move towards circuit racing, criteriums etc. Short circuits can enjoy full road closure and are more spectator friendly. - Majority of cycling fans are riders themselves - they start after the pro's have left, and finish way after the pro's have finished - they never actually get to see the top riders in action. Racing in this country must figure out a way to make it a spectator sport. - More spectators, easier TV coverage, means more attractive to sponsors, more funds available in the racing, higher standard. - Circuit racing can allow the Pro's to do 200km races - raise the standard so we have better success internationally. - Move to a strength vs. strength based racing system based on categories. This allows juniors to come up through the ranks, and ex-pros to race competitively and not be lost to the sport. I genuinely believe that events cannot cater for the needs of the fun-riders and the pro/elite sport. Fun riders are fans of the sport, and are the paying customer, yet they cannot actually be spectators. The needs of the two should be properly catered for, so that both parties get what's in their best interests.

Get him to check how he entered. Now days with a Cyclosport license you can enter the Elite category if there are no number limitations on that category.

Geez, he is in pretty good knick hey!!

If you think cycling is bad, just take a look at the world of high-definition audio! There they talk about all sorts of interesting things that you would only be able to hear if your ears were capable of significant sonic bandwidth, and which the original artist never put in there in the first place, and wouldn't have been able to be captured by the recording equipment used, or stored on a medium that records samples at a rate of 44.1kHz IIRC (but let's not worry about the violation of Nyquist's Law)

Another way to understand the issue here is that the muscles in the cyclists legs are the "engines" i.e. they convert stored energy (in the form of glygogen, fat, and even a little protein) into various forms of energy such as potential energy (lifting the mass of the rider and bike up a gradient), kinetic energy (forward motion) and heat etc. Everything after the muscles in the legs of the rider can be viewed as a "linkage" to transfer the force applied to the pedal, to the force applied by the tyre to the road. This includes the joints/bones in the riders legs, ankle, feet, then the cranks, through the spider, through the chain, rear cassette, hub body, spokes, rim, tyre, then finally the road. Linkages cannot contribute energy (and therefore perform work) to the system, all they can hope to do is transfer that energy as efficiently (i.e. with as little loss) as possible. So, changing the crank length cannot make you produce more power, just like changing the shape of the chainring cannot make you produce more power. But, does changing the length of the crank make the linkages more efficient, i.e. does more of the energy converted in the muscles end up pushing the bike forward? I'm not a mechanical engineer, so I wouldn't want to argue too much about this subject, but I'd assume that there are optimum lengths for the various levers that are providing the linkage in the system. There are certainly optimal contraction velocities and joint angles for the muscles in our legs (based on lengths of femur, fibia, tibia etc as well as muscle fibre composition). So, the rationale behind altering crank length is not about producing more power, it's about losing less power along the way. The force applied by wind resistance is not linear, but improving a 60min TT by 30sec equates to 0.8% faster. 30sec is a significant margin when looking at the performances of pros in major TT's. Can changing the crank length make the power transfer on a bicycle more effiecient by a similar order of magnitude? Possibly, which is why people are prepared to put some research into this issue. I think the issue that needs to be taken into account, is that the difference between say the top 5 TT riders, or the top climbers, is tiny. Any change to equipment that yeilds improvements in small amounts can be beneficial. But that is for top level pro's - which most of us mere mortals aren't

Marco and Jock were riding different cat's - bunch should never have let them go (if they had a choice!)

Copman is that a Pez dispenser or are you just happy to see the camera?

I know that the MTB guys really love them. There must be thousands for KM's of track and offroad around Magaliesburg etc. The guys all download the planned route to the unit and go riding. It's not a big problem if some of the guys are a bit slower, they can go at their own pace and not get lost. I've used my 305 for road rides as well. If I'm planning a ride of a certain distance I can plot it out with the mapping software, check the distance, download the route to the unit and go riding. Bit like a cell phone. When it first came out it was just a very expensive toy which we had lived without for a long long time, now they are indispensible.
