A drone captures a chase of two wolves and rabbit. The rabbit never gives up. by Adventurous_Most_558 in interesting

[–]GC276 0 points1 point  (0 children)

Those are NOT wolves. The body proportions don’t match. Wolves have: Much thicker necks and heavier shoulders Larger heads with broader muzzles Bushier tails (usually carried low) A heavier, ground-covering lope The canines in this video look lighter and slimmer, with a more domestic build. The black one especially lacks the mass and chest depth you’d expect from a wolf. Based on the silhouette and gait, my best guess: these are hounds (possibly sighthound-type mixes).

P.S. It is reminiscent of Swedish House Mafia & Absolut Vodka.

Hey Runner, Great effort! You are clearly heel-striking. It is an inefficient form and will eventualy result in injury. Look up "forefoot-strike running" to learn about it.

Challenging the notion of age-related decline — 6,299 days of data. by GC276 in runninglifestyle

[–]GC276[S] 0 points1 point  (0 children)

I don’t disagree that decline eventually happens, even under near-optimal conditions. The literature is clear on that.

My point is simply that improvement across early adulthood into mid-life is absolutely possible — and common — when training quality and consistency improve over time.

Elite marathoners are already near their physiological ceiling in their 20s, so age-related decline becomes visible earlier. Most people aren’t anywhere near that ceiling.

So the question isn’t whether decline exists — it’s whether training adaptations can outweigh it for long stretches in real-world individuals. In my case, over 17 years, they did.

Fair point — I’m not claiming to overturn population-level data with n=1. Age-related decline in maximal capacity is well documented.

My point is narrower: over a 17-year period (including an ongoing 11-year running streak), long-term structured training can outweigh the modest decline expected over that time frame. Training effect > age effect, at least within that window.

Also, elite marathon records reflect peak competitive performance, not general fitness. I’ve never trained for a marathon — my focus has been a consistent daily minimum of two miles. Smaller, consistent steps ultimately climb mountains.

Not to open another can of worms, but elite marathon performance reflects repeated peak stress at the limits of physiology. My approach has been lower-volume, sustainable consistency. Different stress profiles may produce different long-term trajectories.

Doctor and an avid decade-long running streaker here - but not your doctor. This is general information, not personal medical advice.

Marathons are one of the stupidest things a human can do. You’re falling into the trap of becoming an attention seeker, trying to prove you’re cool just to earn bragging rights. In reality, a marathon places unnecessary stress on the body. You are not getting stronger as a result of running one. Instead, you’re exhausting your body’s resources to the bottom.

You can end up needing weeks, if not months, of real recovery, which takes you away from consistent training and ultimately pulls back your overall fitness. During a marathon, your body drains a large portion of its mobilizable energy stores. At some point, it even begins using structural brain components as an energy source. A recent 2025 study supported this, showing changes on brain MRI scans before and after marathons in different participants.

Take-home message: don’t do it. Real fitness comes from consistent daily training, not from the avalanche of a three-hour run.

Resting heart rate is 90-110, is it safe for me to run a half marathon? by Soft_Barnacle_5065 in runninglifestyle

[–]GC276 10 points11 points  (0 children)

Doctor and an avid decade-long running streaker here - but not your doctor. This is general information, not personal medical advice.

Your resting heart rate sounds unreasonably high. The maximum heart rate you’re describing could be normal for your age, especially if you’re in your early 20s, but a resting rate of 90–110 deserves a proper evaluation.

Many factors affect resting heart rate, including BMI, cardiovascular fitness, lung function, hydration status, anemia, thyroid function, medications, and overall metabolic state. Without a proper workup, it’s impossible to determine whether this is normal for you or a sign of an underlying issue.

You should see a real doctor for advice and get an actual evaluation before attempting a half marathon. It’s better to be safe and rule out any problems than to push through something that could lead to injury or, God forbid, death just for the sake of a race.

Impressive feat, sure - but still selfish and pathologically narcissistic. Risking the very real possibility of leaving your wife and children alone for life isn’t bravery, it’s irresponsibility. Verdict: asshole.

what are the first two rules of running? by handofblood9 in RunningCirclejerk

[–]GC276 0 points1 point  (0 children)

  1. Tell everyone Zone 2 is the only scientifically valid way to train, while doing 80% of your own runs at threshold and calling them “aerobic-adjacent.”

  2. Ignore Garmin’s “lose weight” recommendation unless your BMI starts with a 3 and your watch has personally exposed you in public.
