Note that my post stated “on weekdays”. Among RunKeeper app users, peak is at 6pm on weekdays, as pictured below. The distribution is very different on weekends, with mornings runs being far more popular than evenings.
I agree. So proud of @gpo613!
To be that muscular in our 40’s, 50’s, 60’s and beyond is incredibly hard. Takes incredible dedication to one’s exercise program and nutrition.
BTW, let us know how the whole renewing the marriage vows went in Vegas, which I think took place yesterday? We hope everything went without a hitch and you and your wife had a wonderful time.

And noting that my post was based on Strava data from 2024. I didn’t see any info about M-F vs the weekend.
What year is the RunKeeper data from?
Have you noticed that doing that means that you have less need to use heat or AC when in buildings or cars?
It’s quite old, from the 2010s. However, I think the primary reason for the difference is weekday vs aggregate of full week. The work day has a dramatic influence on running times, so weekday and weekend distribution look completely different.
The graphic below shows weekday RunKeeper app user running times in many countries around the world. There are a lot of differences . A larger portion of persons from India like to run in early morning hours than any other listed country. Swiss like to run during their often 2 hour lunch break (Zmittag). 9-10pm is the most popular hour among runners from China and Korea.
I think Covid and remote work may have changed at least some people’s routines.
In my case, everything changed. I flipped to working out and running more in the AM now than the PM, where it was the opposite pre-Covid.
I’d say I have much different mindset when working out than when I’m working, hanging out or sleeping.
The gyms where I’ve competed have had no HVAC. My gym (where I don’t work) also doesn’t have HVAC.
And there’s a strong possibility that I’ll either be running my November 1/2 in drizzle, fog, rain and/or the cold in November. And I may do another one in February.
In addition to COVID influence, it’s my understanding the Sport Shoes Running Statistics report was also based on a written survey among persons in UK. And the RunKeeper app report was based on 200 million logged workouts in the app, with statistics for USA users separated from other countries. There was a different sample group, different sample method, different rate of treadmill vs outdoor running, different period of year (seasonal temperature variation has big impact), and different years; in addition to weekday vs overall. Across the weekday + weekend, the RunKeeper app results for USA would change as follows.
Weekday – Peak hours = 5-7pm (after work), followed by before work
Weekend – Peak hours = 8-11am (little correlation with typical work hours)
Aggregate Full Week – Peak hour = 8-9am
While most common running times for different groups/countries is interesting (to me), it’s irrelevant for the purposes of Youdon_tsay or other persons reading this thread considering a treadmill purchase. What is relevant is what time they would prefer to run. Based on comments in this thread, I’m guessing Youdon_tsay prefers to run during a time period in which it is uncomfortably hot outdoors this time of year.
Having the option to use a treadmill can change running times from what is common in surveys among persons who primarily run outdoors. For example, I personally prefer to workout late night, so there is less interference with my daily activities. A graph of my HIIT treadmill workout last night is below. Note that I worked out 9:47pm to 10:36pm. If I didn’t have a treadmill (or option to use one at a gym), I would have chosen a different workout time when it was still light out.
I’ve run in 75degree (and hotter) weather….lol, slow regardless of temp but even slower when hot. But it’s pretty dry in Colorado, no humidity concerns. Here at “mile high”, the bright sun is a huge factor. For me a nice overcast day, perhaps wiht a slight breeze, beats a sunny day 10 degrees cooler.
Of course I don’t run as much as I used to. Partly due to age. But mainly due to enjoying pickleball, which has a wonderful social component. It’s lovely making new friends and acquaintances in retirement.

“If people have less muscle to begin with, by age 60 or 70 they can be at a greater risk for developing sarcopenia, clinically significant muscle loss that can affect daily activities.”

Good article. I am about on track for the .54g Protein per pound. They are right that recommendations vary widely.
EXCERPT on PROTEIN:
To help with muscle growth, women, particularly as they age, need adequate protein. And the standard recommendation of 0.36 grams per pound of body weight per day is probably too low, Dr. Phillips said. He advised people — men and women alike — to aim for 0.54 grams of protein per pound. There is no evidence that consuming substantially more protein than that offers any additional benefit, he added. (Some influencers recommend consuming as much as one gram per pound.)

.54 is where I’ve settled as well. Sometimes, I’ll get more than 100 grams and rarely much less, but I find it pretty easy to get 85-100 grams a day.

On the female ‘muscle/strength-building’ front, Dr. Vonda Wright (orthopedic surgeon) has a number of recommendations for strengthening bones as women age. She advocates stressing the bones with a lot of jumping and weights. Hence my box jumps and the mini trampoline now in the family room

There is no shortage of research pointing to benefits of greater than 0.54g/lb = 1.19g/kg, among exercising individuals. For example, The International Society of Sports Nutrition’s Position is summarized at International Society of Sports Nutrition Position Stand: protein and exercise | Journal of the International Society of Sports Nutrition | Full Text and quoted below:
The International Society of Sports Nutrition (ISSN) provides an objective and critical review related to the intake of protein for healthy, exercising individuals. Based on the current available literature, the position of the Society is as follows:
…
2 .For building muscle mass and for maintaining muscle mass through a positive muscle protein balance, an overall daily protein intake in the range of 1.4–2.0 g protein/kg body weight/day (g/kg/d) is sufficient for most exercising individuals, a value that falls in line within the Acceptable Macronutrient Distribution Range published by the Institute of Medicine for protein.
3.There is novel evidence that suggests higher protein intakes (>3.0 g/kg/d) may have positive effects on body composition in resistance-trained individuals (i.e., promote loss of fat mass).
The review below found benefits were notably higher than above among lean athletes – https://paulogentil.com/pdf/A%20Systematic%20Review%20of%20Dietary%20Protein%20During%20Caloric%20Restriction%20in%20Resistance%20Trained%20Lean%20Athletes%20-%20A%20Case%20for%20Higher%20Intakes.pdf is below.
When analyzing the six studies reviewed to determine protein intake per kilogram of FFM, it appears that the range of 2.3–3.1g/kg of FFM is the most consistently protective intake against losses of lean tissue. Furthermore, the goal of the athlete should be taken into account. Athletes with a lower body fat percentage, or a primary goal of maintaining maximal FFM should aim toward the higher end of this range
I regularly listen to the Huberman Lab podcast. It’s hosted by a professor at the Stanford School of Medicine who talks with different guests about nutrition, athletics, health and other topics each week. Most of those guests are research based leaders in their field, such as professors at other universities or trainers with advanced degrees. The most common recommendation of these guests is 1g/lb body weight protein. A minority recommend closer to 0.8/lb or have a variety of qualifiers with different ranges, such as depends on type of protein, type of activities, % body fat, goals, positive/negative calorie balance, meal timing/size, … I can only recall one guest whose recommended as low as the 0.54g/lb, and there was a lot of discussion about why his recommendation was so much lower than other nutrition/athletic experts. As I recall, he was focusing on protein excretion type studies in non-athletes, similar to RDA. He was also a strong proponent of health benefits of a vegetarian diet, which can make higher protein targets challenging.
I personally think 1g/lb is a common recommendations because it is a safe range, regardless of what combination of additional factors are present. For example, it’s more optimal to consider protein recommendations in terms of fat free mass than overall body weight, meaning lower body fat % is associated with higher protein per overall body weight requirements. It also depends on what type of activities you are doing. Weight training and other athletics is associated with an increased protein requirement. It also depends on calorie balance and goals. If you are trying to maintain lean body while in a calorie deficit, optimal protein per lb FFM may be especially high. It also depends on the type of protein. I could continue. 1g/lb is fine for nearly any combination of above factors. The 0.54g/lb recommendation is probably also fine for most persons, but it becomes more important to consider what combination of factors associated with benefits from an increased protein intake are present.

I do a Pilates “jumpboard” class every week to strengthen bones. It’s a little bit of a HIIT workout as well.

Thanks for the good info. I think what we all agree upon is that .36g protein per pound is too low (or much too low). That is from World Health Org, and probably in some countries even that is hard to get. But here is US, lots of nutritional options.

The WHO (and US RDA) recommendation is an estimation of amount required to avoid deficiency among 97% of persons (+2 SDs), as determined by looking at nitrogen balance in artificial conditions, such as when wearing a suit in a lab with little activity. It’s not intended to be optimal amount, so researchers looking at optimal levels for performance, body composition, health/longevity, … often come to a very different conclusion.

@Jolynne_Smyth Over the years I have lifted weights here or there. I am not big at in terms of muscle mass. I am just very lean at the moment, I think the kids call it shredded. Being lean really gives you definition. I have always had a decent base of muscle covered by fat.
The wedding vow renewal over the weekend was great. We ended up having 25 total friends and family (and of course the kids had come) Kids being 24, 24 & 20. We did it an Elvis Chapel. We wanted cheesy and Elvis did not disappoint. Now I need to detox and get back to the gym. Over the 4 days I did only gain 1lb. I was more on a liquid diet 
Also if anyone ever needs suggestions about LV I know way too much about that city.
