Heart Rates

Just out of interest, what are/is your goal? Also, why the sprint finish?

A slight hijack, if I may. I'm currently using an exercise bike, putting in/out about 420 watts, my heartrate can vary from say 140 bpm, to 150 bpm on another day. What is causing this? Hydration? Caffein? Time of day?

Lactate and other remnants left over from previous sessions etc etc

For my interest: For how long are you riding 420w at those HRs? How heavy are you (to work out the usual cycling power metric W/kg)

Generally,20 to 30 minutes, sometimes 40 though, I'm 55, 5' 10", and probably 1 1/2 stone over weight at 14 stone.

Training for an Olympic Tri in June, so just restarting with some 5ks

Sprint finish is because Running on a treadmill is sodding boring.. Only 200 m

Anyway weather was better today so I ran 7miles and never went over 140 bpm

What period of time were you putting out 420 watts? Also the difference of 10 beats between efforts on different days means absolutely nothing.

Either your scale, your hrm or, most likely, the power measurer is in need of a calibration check imo

Otherwise, you should be entering some bike races!

More likely to be your first suggestion

420 watts over that period extraordinary, whatever your weight.

As was suggested earlier, it’s probably the equipment that is not very accurate

If it's a normal exercise bike, then it's basically making that number up so you can't read too much into it. If this is a wattbike, then yes, enter some bike races.

Think your power reading is crap I'm afraid. If you can hold that power for 40 mins then you can probably hold it for 60. Which would give you a W/Kg of 4.7 at threshold which is Cat 1 standard. Unless you have along history of some serious bike training.

420 is massive - I'm pretty new to indoor cycling but I'm maxed out doing 215/220 watts over 20min and and my HR average is high 160's/low 170's

I've got a few friends who can pull some serious pace on a wattbike (300+ watts) - they're amongst the fittest people I've ever known.

But 420 watts would (as has been mentioned) be amongst the elite in cycling.

I barely touch the wattbike and can happily do 220 watts over 30km (38.2 km/h average) - average heart rate was 144bpm, only peaked at 169 (48 years old, 100kg) Over a 10k wattbike session I was at a more useful 277 watts (14m 23). That was an average of 152bpm, peak of 170.

I'd say that I need to spend more time on the wattbike, but it really does get tedious.

I really do need to do more work at higher intensity - max heart rate is about 180, but I barely hit 170 in most training sessions.

Thats interesting. I've got a long way to go. Only started a few weeks ago because of an arm injury so needed to keep doing something at the gym. but think I might stick with it when I'm better. Been pleased that I've got up from just below 200 at the start of the year.

I'm aiming for 250 on a 20min FTP, got a set of cleats on order as I've been told they will make a difference.

Don't compare your FTP to others, there are so many factors and w/Kg is a much better indicator of performance. Some people claim some large FTP figures but they are huge. Myself included, I am 6'5'' and have a pretty high FTP but my watts per kilo is pretty dismal, about mid to top Cat 4 standard.

Even wattbikes spit out total st if they're not looked after, which I am sure many commercial ones are not.

As said, those numbers would be very rare. In a club of 700 I think I could name two people that have ever done over 400w for a 10 mile TT (around 20 min), and we're both larger riders.

HR is a strange one, very individual essentially. Running is very taxing if you're giving it some, especially after a lay off.

400w for 20 minutes is elite level, irrespective of size, surely? It would be in the rowing world.

Its decent for someone around 80kg or below (in the cycling world), impressive at any weight to the layman, but at over 90kg you would't be anywhere near elite doing those numbers

I did 410W for 21 or so minutes in a hilly TT at 78kg and got fking hammered by Jacob Vaughn (Lotto Sudal u23 this year), so its decent, but not top of the tree y any stretch.
