Wildbears, I was some years ago, a semi-serious triathlete (Correction - I did triathlons LOL). This study is more confirmation of what one school of thought professed then. It bears out my personal experience. I was working many, many hours a week and had to find time to train whenever I could. Other guys told me not to worry about it; that I'd be fine so long as I worked HARD in the times I could find. Once in awhile, I could put in a longer easy session.
The results were that my performances were actually better than when I trained more. I think studies like this one now represent the majority view. Thanks for posting it. -
When I was racing back in the 70's and 80's I rode about 300 miles / week.
Way too much!

Cycling Glasses
The Tour requires racers to wear their glasses with the stems on the outside of the helmet straps.
Seems like a safety requirement.Comment

Online, bicycle-tire pressure calculator: https://axs.sram.com/guides/tire/pressure
This has multiple factor inputs.Comment

Tire pressure, tire casing flexibility, road surface, etc...
Tire Pressure is NOT a Maximize or Minimize Variable, but Can be Optimized for your weight, tire size, and course conditions.
Better to set your pressure a few psi below the Break Point Pressure than to have it a few PSI above the Break Point Pressure.
Rough and/or Soft surfaces have steeper Impedance Lines making total rolling resistance higher and Optimal Pressure Lower.
More supple tires will have less steep Crr and Impedance Curves and are more forgiving of tire pressure errors.

Wildbears. Did you see today's Stage 4? Great win for Cavendish. But, what may interest you more is that the solo breakaway rider, who had been away since mile 4 or so, got caught about 100 yards from the finish. Heartbreak, certainly, but he probably deserved to lose it . . . his sunglasses ear stems were inside his helmet strapes!! A fashion faux pas for sure!Comment

Missed it. Is NBC posting race video this year? Good catch with the protective eye-wear stems. -
UCI rules change every year. The information that protective eyewear stems must be inside the helmet straps came from a GCN video from the past. I'll see if I can find it again. -
Yeah, that ear stem positioning is a very big thing. If they were outside the straps and he won, probably would have been disqualified. If anymore rules, laws or regulations are written the forests will run out of paper and the internet out of ink.

TDF is crash city this year.Comment

Crash City for sure! The worst of course was the thing that had her ugly mug and grandpa-grandma sign in Tony Martin's way and knocked down 60+ riders, including all of Jumbo-Visma. Criminal charges are merited, as are lawsuits. Marc Soler is rightfully pissed that he was injured and taken out of the Tour by her antics. I think he is definitely suing her/it unless dissuaded by the UCI.
G Thomas? Crash-o-matic. Someone said he would crash if a bunny gave him a hard look. It was a simple speed bump that knocked him down that everyone else simply rode over.
The promoters? Guilty of bad run-ins to the finish and narrow descents at the end of stages were everyone will want to be at the front.
Sonny Cabrelli crashing Roglic was bad.
Robbie McEwen taking out Peter Sagan was stupid. Sagan has been fined and DQ'd for less than that. At least McEwen got his shoulder broken for it and not Sagan.
But, Tadej Pogacar is a fun kid to watch. Ditto Matthew VDP and others. It is shaping up to be an interesting Tour, even though the odds of Pogacar winning are pretty high after this first week.

A lot of Crop Dusters over our house this time of year. Rode out to the airport to ask what they're spraying.
A couple weeks ago was dry fertilizer and now they're spraying corn for fungus.
This is a Thrush. I have not seen one of these before. Normally in this area you see Air Tractors, Radial engine and Turbo Props.
The Thrush just showed up yesterday.
The guy working on his Air Tractor is from New Jersey.

Training Heart Rate Zones (THRZ) Calculations Using Resting Heart Rate (RHR) And Maximum Heart Rate (MHR)? Using The ??Karvonen Calculation Method
First?,? calculate ?the? Max Heart Rate (MHR)
MHR = (220 - age)
Heart rate reserve (HRR) = MHR - resting heart rate (RHR)
(HRR x 50%) + RHR = lower heart rate of the training zone, that is?,? 50% effort.
(HRR x 80%) + RHR = upper heart rate of the training zone, that is?,? 80% effort.
An example ?using a 50 year old with a resting hear rate (RHR) of 70?:
MHR = (220 - 50) = 170 bpm.
?With a? RHR of 70, the HRR = (MHR - RHR) = 100 bpm.
50% effort would be (HRR x 0.5) + RHR = (100 x 0.5) + 70 = 120 bpm.
80% effort would be (HRR x 0.8) + RHR = (100 x 0.8) + 70 = 150 bpm.
So, in this example, the Training Heart Rate Zone (THRZ)?,? or zones 1, 2, and 3, based on a calculated MHR, ?are? 120 - 150 bpm.
Note: You can customize your zone?s? by changing the percentages. For example, some use 55% for lower and others use 85% for upper.
You can also calculate your Cardiovascular Fitness Age (CFA) using these formulas and working backwards.
For example, my actual maximum heart rate (MHR) is 170 bpm. Working backwards thru the equation, that gives a cardiovascular fitness age of 50.
Age = 220 - measured MHR = 220 - 170 = 50 years old.
And my measured training zone would be:
HRR = MHR - RHR = 170 - 40 = 130 bpm.
50% effort would be (130 x 0.5) + 40 = 105 bpm.
80% effort would be (130 x 0.8) + 40 = 144 bpm.
THRZ = 105 ?and? 144 bpm for 50 ?and? 80% effort.
Here's another source for determining your THRZ that considers both resting HR and activity level/conditioning state: Interactive Tool: What Is Your Target Heart Rate?Last edited by wildbears; 08-16-2022, 09:34 AM.Comment

Maximum Heart Rate and Heart Rate Reserve
The online literature is disparate in how to mathematically calculate these rates.
Additionally, some sources give examples of calculating training zones where the math is done incorrectly and the results using MHR versus HRR show little overlap.
The general consensus is HRR is more accurate for the calculations as it factors in the Resting Heart Rate (RHR).
However, at this point, I'm thinking the best determination is by measuring the actual MHR during HIIT exercises.
Here are 3 articles I've reviewed with varying results:
https://www.menshealth.com/fitness/a...ning-workouts/
http://kalamazooarearunners.org/maki...reserve/page/2
https://www.runnersworld.com/advance...of-the-matter/
Note that resting heart rate appears not to be the same as your asleep heart rate. The resting heart rate is measured when you are awake and up but not active.
Mine are 55 and 32 bpm.
So, depending on which number I use, my training zones could be off by 30 bpm.Comment
