comment Is contact patch area governed by A=W/P
@Criggie I don't think the surface area will necessarily be the same. Imagine a spectrum of casing stiffness from steel to very supple. A perfectly stiff casing will have virtually no defection (regardless of pressure) and infinitely small contact patch.

comment Do higher speed crashes result in less serious injuries.
Unfortunately the answer is premised on anecdotal evidence. For example, I have seen the worst crashes on sunny days... therefore sun must cause bad crashes.

comment Is contact patch area governed by A=W/P
I actually want to try this at home, with two equally sized tires, one very supple, the other with a very stiff casing. I am willing to bet the contact patch is not identical.

@Vorac - It's science! Don't forget to include some replication so that the effects of measurement error can be accomodated. If you are statistically comparing different tires your stats model will also need to accommodate the subsampling. I can help if needed.

comment Nutrition during long rides while reducing fat
While not explicitly requested by the OP, I just wanted to bring up the importance of fluid intake on long rides. Without adequate hydration the body cannot make use of the consumed calories. Many underestimate hydration needs (drinking too little too late) making keeping on top of hydration can be difficult for most riders new to distance riding.

comment Training for long distance rides (> 200km)
Andy P - It could be useful to include some a rest week or two and a tapper down period prior to the event in your example program. Even if you don't make the target goals, coming into the event maxed out will likely lead to failure. Coming into the event sufficient rested will increase the odds of success (even if training goals were missed).

+1 to @ilikeprogramming for mentioning bike fitting and contact points. Without putting time on the event bike there is no really way to know if the bike will work for the OP for that period of time.

comment optimum frame size for very small 5'2" female
@Frisbee and you have never had two flats in one ride? Plus you don't have anything to lend others. 700c on the right frame can work fine for smaller riders. 650b has some advantages plus a lot of bike geek buzz. Most non-geeks would benefit from cross comparability over niche bike-geek cool factor.

comment optimum frame size for very small 5'2" female
650b is a nice option for smaller riders, but it is not a common size in road cycling. At races or charity rides neutral wheel support will only have 700c. On club rides no one will have 650b tubes. Unless you are only riding on your own, nonstandard wheel sizes can be a hassle.

@SuspendedUser the notion that on average women have longer legs than men is actually a myth. Empirical data says otherwise.

comment Are road brakes designed not to brake too much?
@birthofearth - I am sorry, but the emphasis of "brake modulation" by rim brakes is marketing fluff (turn a -ve into a +ve). Brake modulation and braking power are not mutually exclusive characteristics. Hydraulic disc brakes have arguably better modulation, power and consistency and are making in-roads into race road bikes (2015 onward).

comment Are road brakes designed not to brake too much?
@whatsisname - No advantages? How about in the pouring rain when rim brakes essentially do not work until you clear the rims of water? How about in wet and freezing conditions? How about better modulation so that you can brake consistently right up to but not over the point of lockup?

@DanielRHicks cleaning is a good time to inspect. I can't tell you how many potential problems I caught while cleaning... Too many to count.

comment arm and elbow position — sticking out or straight, also pushing or pulling on handlebar
@NorthKrimsly - I meant stackexchange is not the best forum because no one else cannot directly observe you. Getting different opinions from different experts is not uncommon, especially for bio-mechanical issues. I personally made the best progress integrating information across three physio therapists, each had a unique perspective, but no one had the complete picture on their own. Unfortunately, it can be hard to fully understand what is going on in a hour or two session. We often need to be our own best advocate by continually compiling and re-assessing information from all sources.
