People are saying they can ride all day but only run for a few hours etc.. Well the same can be said I can hike/walk ( that would be like coasting or soft pedaling ) all day 10+ hours but I would die on bike trying to maintain 23 mph for any length of time.
This about sums it up for me. Running requires a minimum amount of effort that is far higher than the minimum effort required to ride a bike - at least on level ground.

I can ride all day at a relatively low effort. But I can only ride for approx 1 hour at my FTP.

Steep hills also dramatically increase the minimum effort required to ride a bike. Above a certain grade riding inevitably becomes harder than the minimum running effort on level ground. Again, while I can comfortably ride all day on the flat, I can only ride for a few hours up fairly steep gradients. Would an Everest riding attempt be harder than a running a marathon?

Once you get on the bike, you forfeit the option to make excuses.

Hard disagree, it was hard to get back on the bike after the crash, I think most people would have went to the hospital. The front gate at work was shocked when I showed up covered in blood

If you had passed that woman, do you think she would be on a forum now making excuses?

No more excuses. Pantani wouldn't have let that woman pass him, even if he had a broken leg.

"G" rode with a fractured pelvis and dislocated shoulder. He said he felt like a million dollars when it popped back in, lol.

Over the decades, I have run 15 marathons and I guess ridden maybe 100 long rides in the neighborhood of one hundred miles or so.
Running a marathon is about equal to a 100 mile ride.
But a marathon, a week after a 2 day (100 miles a day) ride, is tough.

No idea whether there's a "conversion" or even a typical method, with such a thing.

Estimate: ~8mi run and 40mi bike. A few decades ago, when I did hard long-distance running, I also did lots of hard 20-40mi rides. Generally speaking, if I pushed briskly on each run and bike effort, I'd estimate the equivalency at roughly something like 8mi run to 40mi bike. As it turns out, that's roughly the difference in the Iron Man Triathlon distances for bike and run.

I know this doesn't apply to me now, given that I no longer run and don't ever do a "pushy" ride. No idea whether this estimate would apply to anybody else.

When I think of a run, it's in a race.
When I think of a ride, it's in a named ride (often with rest stops).
So my intensity level is higher in a running race than in a ride.
