Now then chaps, im not sure but i think i might have a problem?
You see, i suffer from quite a high heart rate, just below 100 at rest, usually peaking at around 190 when working hard up the hills.
Recovery not too bad, average around 160 on my regular ride of around 36 miles / 1:53 hrs.
However, me and my buddy went from home to the white horse in North York Moors, with its pair of 1 in 4 climbs, one alongside the horse and the other up sutton bank, i knew i was struggling all day and when i returned home and plugged in the Garmin Forerunner 305, i noticed a massive peak on the graph.
IMAGINE MY UTTER SHOCK AND HORROR AT THE FIGURE STARING BACK AT ME - 255 BPM!
IS THIS PHYSICALLY POSSIBLE WITHOUT HAVING SUFFERD A MYOCARDIAL INFARCTION?
I HAVE NEVER HEARD OF ANYONE HAVING A HEART RATE THIS HIGH AND SURVIVING.
SHALL I PUT IT DOWN TO A BLIP ON THE GARMIN OR DID THE 110 MILER REALLY TAKE ME TO DEATHS DOOR AND BACK?
I AM BOOKED IN TO SEE THE QUACK ON THE OFF CHANCE JUST TO BE SURE.
ANY OTHER IDEAS?

255 happens to be the maximum value you can store in 8 bits so it's possible that some external source (power lines, etc) overloaded the device. I see similar effects on my wireless computer along a certain stretch of road - 107mph on the flat is, I fear, pushing it, even for me.
On the other hand, you could be the first person you've heard of who's had a heart rate this high and survived. 
And be very wary of any quack's diagnosis - they specialised in administering drugs to the sick, and know very little about health.

Very high heart rates are known when someone slips into tachycardia. When the heart flutters it can reach to over 200 easily. You may not be aware of it at the time.
As to a maximum ordinary rate?
I'm not sure but would imagine that your body would cut in and you would faint rather than drive your heart to destruction.
Be very cautious though. Does your gizmo not tell you your heart rate at the time. If it does you can rein things in as you go.

I've written this somewhere else, I don't read the fitness forum much, but I regularly hit 240 when riding hard up the (not especially big ) hills round here. It's been the sane for the past 16 years since I took up cycling properly.
When I was particularly fit, my resting rate got down to 55bpm, but ,with little training is now about 70.
That 240 "max" hasn't changed at any point.I am fairly skinny and always have been. Incidentally, I don't know if this is connected; 1.e. genetically, but when my partner was pregnant both my daughters had to be monitored occasionally, in utero, because they had high heart rates.
Lets hope I don't drop dead soon.

Sounds like you're a fast beater, wuverley. Don't worry about it - there's no such thing as a "right" value, in spite of what the medical profession would have us believe.

I'm 54 and working on losing some weight. I started riding again about 6 weeks ago. Yesterday I did an 18 mile ride at the end of which I decided to see how I'd do with a sprint. The ride is flat with only a few dips and rises. I road flat out for the last mile and noted that my Polar FS3 was blinking 186 (which is the top end of the zone I had set.) When I checked the workout stats I was surprised to see that the max heart rate was 229. My legs were shaking a bit when I finished so I know I was deep in my anaerobic zone. I found this site while googling for some information about this kind of heart rate. I felt fine after a short recovery so nothing seems amiss. I'm not sure whether or not to worry about this.

I don't know if you, personally, should worry about this, but I've always had a high max heart rate and, as scm says, I've never worried about it because it's always been the same, no matter how fit or not I have been. So I've assumed I'm fine.
If you're genuinely concerned go and see the doc, it is his job after all. The trouble might be that if you don't seem to be ill in any way he probably won't be interested.
There is quite a variation in human physiology, and some people seem to have higher natural heart rates than others
Don't stop cycling though

Would you worry about it if you hadn't seen your heart rate stats? Your body will tell you if it's suffering far better than any poorly understood numbers.

My max 'should' be 190 going by all the old guides. I regularly hit 208 when spinning.
I solved this problem by not taking my heart monitor with me as I felt fine at that rate!

There is something bizarre about pulsemeters though, especially Polar ones that I've used. I can be freewheeling down a hill (I know, I know, I should be training down them as well...) and the display will jump to 240 or 250 from the normal 100 to 150 nwhere I woud expect it to be. Outside interference? Well if that is so, why does it read normally going up the same hill? Only occurs going downhill, and on various hills as well.

You're on a different side of the road going up and down, and maybe the interference only reaches one side? If it's an underground cable at the side of the road ....

I'd be inclined to agree with this. A spike of 255 rather than a sustained freakishly high figure would probably suggest a technical blip, but I'm no doc!

i have stopped using my heart rate monitor cannot rely on it. my job is to do with radio control we use 5 frequenceys the highest being 2.4 gig a few weeks ago we had a interferece problem, it turned out to be a cracked metal fin that was causeing it,broke the piece of and no more trouble.

My Polar occasionally does the same thing - usually when I've been overtaken by a car or similar. It's obviously getting a few extra signals and getting confused.
The original poster's resting and recovery heart rates seem generally very high though, although we don't know how old he/she is - 190 peak if you're 20-odd is nothing. If you're 60-odd it's quite high! Definitely worth talking to the doc and getting blood pressure looked at as well.
FWIW, I'm 42, resting rate 50, can't usually make myself go above 180 in normal training, but can hit mid 190s in a road race sprint.

The Maximum safe human heart rate as adviced by the medical profesion is 220bpm - the persons age.
A resting pulse above 100 is considered a possible indicater of
tachycardia and is worth talking to your doctor about.
Given the number of cyclists and runners who suddenly drop dead while training this is a subject worthy of serious discussion.
While on the subject of health...dispite what anyone sais to the contrary training while you have a cold is NOT a good idea and is putting yourself at unnessecery risk. The benifits of resting up far outweigh any loss of fitness that may incur.

What is it with the scinisism of the the medical profession often exspressed here?. A high heart rate is NOT a good thing...the heart isnt working "better" cus its faster!
Perhaps its some kind of Macho Bullshit thing that some of you are exspressing??!!!.
Like this noncense bout head colds v chest colds....its a virus in the blood you plonkers..it dont differentiate!

Agreed - no difference, place a toad on your head, wrap seaweed around your neck and rub mustard on your genitals. Fine in a day......

I aint sitting on no mans head!! (Toad being El_Cids description of me) But I agree, if I can get up a 25% hill at 170bpm as fast as someone else at 220bpm surely that means some part of me is fitter or stronger whether heart, legs or whatever. I heard once that all animal hearts beat roughly the same amount of times in a lifetime whether a mouse at 300bpm or elephant at 25bpm. We should be the same surely?! So when your number is up it really is a true saying! Our heart rates rise high when training but are slower on average than the general public, while Mr I.m Blobby thumps away quite fast all the time, therefore we live longer..I did hear that on Roy Castles Record Breakers or something when I was 11 so it may not be totally scientific but it sounds logical to me.
