I love it. one season is perfect. lived on east coast two years. really didn’t like those white stuff falling from
sky in winter time. and rain ugh....

Just wanted to retract some of my previous reservations I've expressed here about high intensity cardio workouts. Bike nuts seem to be good to go -- the nuttier, the better. This paper just out:
Association of Cardiorespiratory Fitness With Long-term Mortality Among Adults Undergoing Exercise Treadmill Testing
"Question What is the association between cardiorespiratory fitness and long-term mortality?
Findings In this cohort study of 122 007 consecutive patients undergoing exercise treadmill testing, cardiorespiratory fitness was inversely associated with all-cause mortality without an observed upper limit of benefit. Extreme cardiorespiratory fitness (≥2 SDs above the mean for age and sex) was associated with the lowest risk-adjusted all-cause mortality compared with all other performance groups.
Meaning Cardiorespiratory fitness is a modifiable indicator of long-term mortality, and health care professionals should encourage patients to achieve and maintain high levels of fitness.
Abstract
Importance Adverse cardiovascular findings associated with habitual vigorous exercise have raised new questions regarding the benefits of exercise and fitness.
Objective To assess the association of all-cause mortality and cardiorespiratory fitness in patients undergoing exercise treadmill testing.
Design, Setting, and Participants This retrospective cohort study enrolled patients at a tertiary care academic medical center from January 1, 1991, to December 31, 2014, with a median follow-up of 8.4 years. Data analysis was performed from April 19 to July 17, 2018. Consecutive adult patients referred for symptom-limited exercise treadmill testing were stratified by age- and sex-matched cardiorespiratory fitness into performance groups: low (<25th percentile), below average (25th-49th percentile), above average (50th-74th percentile), high (75th-97.6th percentile), and elite (≥97.7th percentile).
Exposures Cardiorespiratory fitness, as quantified by peak estimated metabolic equivalents on treadmill testing.
Main Outcomes and Measures All-cause mortality.
Results The study population included 122 007 patients (mean [SD] age, 53.4 [12.6] years; 72 173 [59.2%] male). Death occurred in 13 637 patients during 1.1 million person-years of observation. Risk-adjusted all-cause mortality was inversely proportional to cardiorespiratory fitness and was lowest in elite performers (elite vs low: adjusted hazard ratio [HR], 0.20; 95% CI, 0.16-0.24; P < .001; elite vs high: adjusted HR, 0.77; 95% CI, 0.63-0.95; P = .02). The increase in all-cause mortality associated with reduced cardiorespiratory fitness (low vs elite: adjusted HR, 5.04; 95% CI, 4.10-6.20; P < .001; below average vs above average: adjusted HR, 1.41; 95% CI, 1.34-1.49; P < .001) was comparable to or greater than traditional clinical risk factors (coronary artery disease: adjusted HR, 1.29; 95% CI, 1.24-1.35; P < .001; smoking: adjusted HR, 1.41; 95% CI, 1.36-1.46; P < .001; diabetes: adjusted HR, 1.40; 95% CI, 1.34-1.46; P < .001). In subgroup analysis, the benefit of elite over high performance was present in patients 70 years or older (adjusted HR, 0.71; 95% CI, 0.52-0.98; P = .04) and patients with hypertension (adjusted HR, 0.70; 95% CI, 0.50-0.99; P = .05). Extreme cardiorespiratory fitness (≥2 SDs above the mean for age and sex) was associated with the lowest risk-adjusted all-cause mortality compared with all other performance groups.
Conclusions and Relevance Cardiorespiratory fitness is inversely associated with long-term mortality with no observed upper limit of benefit. Extremely high aerobic fitness was associated with the greatest survival and was associated with benefit in older patients and those with hypertension. Cardiorespiratory fitness is a modifiable indicator of long-term mortality, and health care professionals should encourage patients to achieve and maintain high levels of fitness."

One interesting finding buried in the data which has also been reported in other recent studies...
"The prevalence of associated comorbidities decreased significantly with increasing performance with the exception of hyperlipidemia, which was present in 31.6% (1128 of 3570) of elite performers and only 25.1% (7323 of 29 181) of low performers (P < .001)."
So get off statins. High cholesterol (including the "bad" one) is not how arteries get "clogged up".

So I guess that bears out the anectodal evidence of all the 70+ year old cyclists I see crushing it around Marin

"Question What is the association between cardiorespiratory fitness and long-term mortality?
Who wrote the question?!
I think I can offer a pretty good guess at the association between anything organic and mortality.
Keynes a while back produced a zinger on long distance running and death.
What's short-term mortality like, anyway? Sounds like a cool option.

^ u are so right...
as soon as I got home from GA this afternoon I took the car out for a 13x mile blast...,
life is so much better afterwards.

^ wow... is that why PAG is behind schedule? too busy killing moles?
I didn't ride today..
so I got in trouble
