Power Output and VO2 max

But I also remember a few 'thought to' and 'believed to be' disclaimers in there! These processes are not yet fully understood and may be different for different people. Good luck with your course!

Thank you very much for your prompt answer SideBurn. Your answer is very helpful and has clarified what I thought i.e.. power output continues beyond VO2 max but using the anaerobic (lactic acid) pathway.

That is how I understand it!

Power Output and VO2 max

Not sure what you are asking here;

VO2 max is simply the point at which your body cannot take in any more oxygen, it is not linked to your maximum power output. You can continue to produce more power, but it is thought that this power is produced in a less efficient way ie anaerobically.


Or are you asking how that power is produced?

You would continue to use energy as before, presumably adenosine triphosphate (ATP) the lactic acid produced can be recycled and used as energy. Pyruvate provides energy but in a slightly different way according to whether it is produced aerobically or anerobically.

I would have to dust the books off to provide an authoritative answer! This is from memory; has this helped at all, or am I off target completely?

It was considered OTT at the time 

My thoughts are that Jaylo should already have a reasonable 'base'?

'Olympic' is only 25 miles, I am thinking 15 to 20 mile ride followed by a 'turbo' session? 40/20's 40 seconds hard and 20 seconds rest. Do about 10 of these.

Apologies for slight off topic here but I have just seen this article;

Just to be clear, this is how some teams used to do it i.e. miles, miles, miles and more miles with a garnish of miles! 'Speed' came from lots of racing.

But, to the point, they are riding about three quarters of the distance of the target race (Tour of Flanders). Today Team Sky are all about quality, not quantity. It is also worth remembering that 200km is about 5 and a half hours riding time!

Instead of asking how much, try thinking variety (quality), fast, slow, turbo (static bike) a few weights, group, solo etc. I would suggest that you should focus on speed and not distance or stamina.

Don't get into a routine!



SAD - He says running is making me look old and drawn

Posted: 09/01/2015 at 08:57

I am not sure what his problem is here; we are all getting older, most of us are getting older and fatter. I get the, "you are too thin" speech from time to time from various people. I just say to them that when people say this it means I am nearing my racing weight, a few more kg's off should do it! This usually shuts them up.

50 km a week is about 5 hours a week? Out of 160 hours in a week? So I do not think you should feel guilty about time spent running. Do not give up something you enjoy because your husband says so.

But can you be too thin? How do you score on a BMI scale? I am at the bottom end of the normal range and I am happy with that.


ultras in south wales /west

Posted: 09/01/2015 at 08:26

The first Ultra in South Wales that I can find is 28th of March

Otherwise there is an Ultra in South Devon 7th of February I am doing the Marathon.

Any event this time of year is going to be at the mercy of the great British weather. I did the Might Contain Nuts event in 2013 in heavy snow, 2014 in Arctic like conditions and the South Devon event in 2014 had high wind and hail stones  Be careful what you wish for

Running and Cycling, how much can I expect?

Posted: 23/12/2014 at 09:41

All I can assure you of is that cycling will make you a better runner. However I am talking as someone who is a good runner and uses cycling to maintain fitness, particularly whilst injured.

Whilst cycling and running both use your leg muscles the muscles are used in different ways. So I would suggest that you should incorporate cycling into your running training not replace it, unless injured of course.

The way it can help is by increasing your volume of training, as in the number of hours you train. I would suggest that an hour of cycling is as good as an hour of running and much less likely to injure you. It also adds variety and targets other muscle groups.

I find that cycling and running work particularly well when combined, for instance cycle to the parkrun, run then cycle home. The combinations are endless! And all add variety. 

Blood sugar issues

Well, If I want to induce low blood sugar levels, I eat nothing for maybe four or five hours, and just as I'm wanting something to eat, I have a nice glass of orange juice. I then go for a run. 

About 5 minutes later, my vision starts going. If I shut my eyes I can see two bright patches that resemble each side of my brain. I go dizzy. My energy levels drop out the basement. I sweat up like a pig and feel so hungry I could eat dead things on the ground.

Running is impossible due to balance issues. Its walk home and start eating. A while later another diet has been shelved.

Try it.

When mine are low I just feel like I have wet cheeks and cannot think straight; but I have access to a blood sugar testing kit, so I know that this feeling is low sugars. But not everyone has access to one
