Bike Mileage to running mileage?

You really should measure your maximum heart rate for whatever sport you participate in. There are few sports where you can max out as high as when running. Your arms are in motion and you have your body erect and stride in motion (against gravity) so you will find that your maximum HR will differ from when you are cranking as hard as you can on a bike. Similarly when swimming your body is horizontal and will get a different max if you were to measure it. The tri guys train with sport specific HRMax. One benefit of biking is you can keep your HR up for five hours straight, turn around and do it again a day or two later. Downside, takes a lot more time out of your schedule to get similar benefit. Not a bad substitute when injured.

i have sex for 5 hours a day....how many miles of running is that?

Thanks!

I've always felt it is a time thing (for aerobic training, not running specifically as you are not running), with a 2:1 ratio being the ratio (1 hr biking same aerobic benefit as 30 minutes running)

The mileage thing that was listed with exponential factors on bike speeds assumes one is riding on the same bike on the same surface (most likely road bike on the road). However, there are many different types of bikes and surfaces that would affect the mileage ratio. Therefore a time ratio would be better. For example from experience:

Road Bike 22-23 mph = Mountain Bike 17.5-18.5 mph(on road) = Mountain Bike 15-16.5 mph on gravel/dirt (depends on packing). Of course this would assume the elevation changes are similar

Stationary Bikes can't be included as the calibrations are very different.

Basically just go by hr (keep 150-170) and rpms (90-120)

new question ..... if some one is injured for a long period of time and they bike a lot, won't they come back with thunder thighs, not the best for distance running? thoughts?

Kind of a stupid question, but shouldn't rest and healing be your primary concern, and not whether or not your getting a solid workout?

Anyways, I don't think it's necessary to get a HRM just for your month of rehab, unless you plan on using it for running as well. You should be able to tell whether you got a good workout or not, and 22 mph is pretty good for a runner cycling for rehab.

HR on bike vs. running is apples and oranges, and it is highly unlikely that you will get near your running HR on the bike, at least not for any sustained amount of time.

Yes I probably should be more interested in rehab and what not, but I don't have patience, and that is a big problem.

After sitting on my a** for a while I just can't take it and the docs said if I don't feel it on the bike that I can try that, so I will. Problem is if it gets any worse I can't keep going and seeing the docs b/c I don't have the money for that.

Just trying to give a competitive (ok more like mildly competitive) running career a shot. (by that I mean win some road races, hopefully pr)

That's right ... just as hard as running!

it's harder than running.

Well good luck, but just ride, and don't worry about the running equivalent. They are so fundamentally different, cycling should just be considered cross-training, not a running replacement.

Probably the best thing said yet on this thread. No amount of cycling will make you as good a runner as running will. The muscle groups used are quite different, as well as the power requirements (cycling is actually much more of a short-burst high-power sport than running, despite the longer distance and time you can go). Basically, use it as an aerobic conditioner, but realize that you'll have to do work to regain your running form and the muscle memory that goes along with it.

When I was 30 I biked 140k a week and did not run.

That is the only exercise I did.

I entered a 6k run on a whim and ran 24mins and change.

24 years later I run near to the same splits for a half Marathon on 60k running a week.

What kind of heart rate are you getting when you run? This statement doesn't make sense. My heart rate when I run stays in between 100 and 120 bpm. It's been all the way up to 210 bpm on the bike, but usually stays between 160 and 190 bpm. Maybe I'm just not running hard enough, or you are not spinning at a high enough cadence to get a solid cardiovascular workout in on the bike.

100-120???

at 100 you must be practically walking. My HR is rarely ever below 120 when running. It is normally in the 130-150 range.

ave heart rates from the last year....

153 for runs

137 for biking

.

to be fair, the biking i do is probably the equivalent of my long/easy runs and doesn't include any "tempos/speedwork"

what? that's 25mph average for the whole tour. averaging all terrains, including the mountains.

it does NOT get easier after 3 or 4 days, or sprinters would not be DNSing once they hit the mountains.

Yes that's right, they average 25mph for the whole tour including mountains.

It does get easier after 3-4 days, the first few stages are insanely hard with constant attacking. After a few days they amount of attacking eases up gradually.

no. no it doesn't. each stage of the tour, indeed any stage race, features constant attacking until things settle into a pattern. this has nothing to do with difficulty, but tactics. tactics for GC riders, stage hunters, KOM and sprinters.

i'm still not sure what you mean by "it does get easier". if you mean it settles down somewhat as a tactical race, sure, but you ride hard every day for a week and see if the next week is easier.

It does get easier because the first few days of racing in the mountains your body is just not used to it. Especially after days and days of racing on the flats. Ligget and Sherwen remark on this all the time in their tour coverage.

Remember that easiER does not mean easy period.

It takes you 5 hours to nut during sex? Man something's gotta be wrong with you. I'd hate to be your mate.

I second this and was surprised that it took so long for someone to say this explicitly (I think the 22 miles riding and 0 miles running said it well - in a smart ass way).

While biking is aerobic conditioning there is much more to aerobic conditioning than the heart. Crucial to aerobic conditioning is the development and maintenance of the sport specific muscles (including the vaculature, mitochondria, aerobic enzyme activity, fiber type, etc.). *This* is why a world class biker is a thoroughly mediocre runner without training - because the running muscles are not developed, only the biking muscles (there is only partial overlap).

So why not deep water pool run? This is much more running specific, in fact, probably the most running specific acitivity for the injured. Google Pfitzinger and deep water pool running to get a schedule
