world bicycle record over 12 hour period set(9 posts)

world bicycle record over 12 hour period setBreck

Since Distance or "Endurance" is capturing some attention on the Board now-a-daze in light of Doug Sloan' Epic ride, may I submit the following if you missed it ...

"... Four-wheeled vehicles of all shapes and sizes will be part of a busy weekend
at Lowe's Motor Speedway, but Tuesday's story was a world record of the
two-wheeled variety.

Chris Harkey, one of America's top amateur cyclists, set an outdoor world
record for miles completed on a bicycle in a 12-hour period by pedaling
192.72 laps around a 1.434-mile course on the apron of the speedway between
6:21 a.m. and 6:21 p.m.

That's 276.37 miles - about the distance from Charlotte to Richmond - to
break the previous mark of 272.06 miles, held by Paul Solon.

[average pace = 23.03 mph. And track courses rule IMHO regardless other
"conditions", etc. -breck]

Conditions were less than ideal for Harkey, a 29-year-old from Mount
Pleasant, N.C., who tried for the same record one year ago and fell an
agonizing 1.79 miles short. It rained during the morning and Harkey spent
another part of the day battling the wind.

"I was trying to figure out what else they were going to throw at me,"
Harkey said.

"The fifth and sixth hours were really tough. The rain was coming down hard
and I thought the day was over, but my trainer and coach Jim O'Brien talked
me through it."

H.A. "Humpy" Wheeler, the track's president and general manager and an avid
cyclist, presented Harkey with a $5,000 award for his successful effort.

"I was broken-hearted when he came so close last year," Wheeler said. "He is
a great athlete and cyclist and I am extremely proud of what he accomplished
here today ..."

post note by breck a. leath.
(am changing from wade kelly as he has a bike novel race to finish[!]).
It's hard to keep up with distance records now a days for us more "endurance" inclined athletes (i use the term sparingly in my case). Way back in the 1960's a long distance runner was considered 10 miles or more by us old card carrying American AAU members. The Marathon became enormously popular after Frank Shorter's Gold in the 1972 Olympics and everyone started "doing it" and on precious few training miles too. We "true" distance types believed ~80 miles a week base and throw in some dieting fasts to get the body to adapt to fat "burning". Later "fasts" were watered down to "fruit juices" only one of the days and later -now- all this energy drinks, gels, etc. are supposed to take up the slack and replace the on-road training IMHO.

In the for-what-it's worth-cat some running "ultra" records (or were as can't keep up) Bike Vs Run. Approxs are given as am more interested in the ratios than the exact times (which would have to triple or at least ~2.73 (ave.) verify.
One Hour [ Bike, ~35 miles; Run, ~13.3 mi. ( ~2.63 ratio)]
12 Hours [ Bike, ~276 miles; Run, ~ 98 mi. ( ~2.82 ratio)]

Am working on the Equivalent Energy Problemo as brought up by the "Marathon-Bike" Problemo. The problem there is that there are two variables, one being distance and the other time. That is one has to know both ones marathon (distance) and time at the outset (on a given course and day), and then equivalent the bike distance and time to obtain "equivalent energy". Believe the "best" solution may be to use Kenneth Cooper's Aerobics table equations for the bike and run; set them equal, and solve. If you have any interest to try this, and we may compare notes.
The equations are:
Bike: Equivalent Energy = (6X(distance)^2)/ total time
Run : Equivalent Energy = (40X(distance)^2)/ total time
where (distance)^2 = distance squared (distance x distance)
(have ever so slightly simplified the equations but would be <2 pts delta)
This would show for instance that a 5 hr Century would garner 200 "points" in Cooper's Aerobics Table where as 3 hr Marathon (the coveted standard) would ga

And the One Hour listed above would yield 122 pts Bike; 118 pts Run, & the 12 Hour listed above would yield 635 pts Bike: 534 pts run. The 12 hour diff could be explained simply by those that took up the gauntlet (biking glove?, as we SoCal runners typically don't wear them) or minor adjustments needed for the Factor, or other Limits yet unknown, aka anomalies to theorists.
Tricky Business Peety & if you re-thought your "quick and easy comparison", well so did me, as thought you had the idea but did not re-post ... mee too, slippery slope, etc. :)

that doesnt sound healthyishmael

not for me..5000 dollars isnt enough..maybe you could do a study of how many years are cut off of a life span from doing such a thing...actually i would maybe do it if i could but im nowhere near able..
Lifespan is measured in heart beatsBreck

An ol Yogi belief.

The fitter one becomes the lower the resting heart rate. Stressing the heart within limits is a way to lower the heart during those times of un-stress, i.e., the other 23 hours of the day if you spend an hour a day exercising.

Do the calcs:
Ave male with ~70 beats per minute no exercise Vs fit male with ~ 50 or less beats per minute exercises one hour a day. If the heart muscle has a fixed total number of beats before over-haul (major or minor) or death, then who lives the longest.

No one has ever claimed that hard racing in and of itself is healthy. But who really does it. Maybe the top 3% of the elite of the elite. The rest of us reach an intolerable pain limit long before that threshold is met.

One mayest be run over by a truck whilst riding the bicycle eating the carrot. Does it now follow that carrot eating and bicycle riding is bad for thou health. Logic has it's limitations.

That is amazing. I mean, we all have done centuries. Some of us have done double centuries. At 23mph it is stunning. This defies logic. I am suitably impressed.

How could this be unhealthy?

If you finish it without dying, you win.

Adventure Racers (Eco Challenge and the likes) veterans are among the healthiest walking this earth. They submit thier bodies to far worse conditions than this bike ride over a period of weeks. I dont see how this bike ride could shorten your life span.

it seems so grueling that it could be damageing..maybe not..there must be a limit of endurance at which point its not good for you, dispite the obvious instant death...then again maybe that just the american in me, maybe its good to fast and get your body to experience harshness..if i skip even one meal i feel like a big poo..

Sorry to be a bit of a pedant, but this one showed up on about a month ago.

There was some discussion as to what constitutes a world record as a result. Are there set rules for this type of event?

Reason for asking: the UK Road Time Trials Council run a 12-hour time trial championship annually. They have fairly strict rules on drafting, and so on. To get to the point, their 12-hour record ( is listed as 300.27 miles by Andy Wilkinson. He also holds the 24-hour record with 527.07 miles. And to cap all that he also has the "End-to-End" (also known as Lands End to John O'Groats) record which I think is less than 48 hours (but I might be wrong...). That's about 800 miles or so.

I'm not faulting the claim, as the rules may be different. It does seem likely that other people may have ridden further in a 12-hour period though.

Some "disciplines" such as the one you mention and the Ultra Running Community on the running side try to keep it kosher as within limits and fair rules of play.

Typically here in the States, all road running course events from 5k thru the marathon that are certified are so stated. Most running forums cuss and discuss this subject thoroughly as to "comparable" times. I.e., your "great" 10K time Vs my "lousy" one due to course, etc. Total bike-wheel calibrated distance; point to point distance from start; allowable maximum grade; etc., all figure in.

If any interest, check out:
(an interesting read for anyone)

Would likewise be interested in Bike website of similar nature.
