I think that's what it is? I only ever experience this at that intensity on a track though or in the last KM of a race. I could be completely wrong of course, hopefully DG will come along with the right explanation.

Myles Splitz wrote: » Blood lactate (or as often mistaken as lactic acid) is a bi product of the energy production process. Depending on work level we either produce energy with or without oxygen. This bi product also releases hydrogen ions which result in fatigue and is normally produced at a higher rate in the absence of sufficient oxygen. Think of it as the following 1) Aerobic Energy Pathway. Consider this our "Solar Power" if you will, it has a significant set up cost but once established it can be used for sustainable energy and produce less harmful waste products 2) Anaerobic Energy Path way. Our Fossil Fuels. produce a highly effective energy source but is finite and produces waste products that are harmful to the enviroment (our body in this case) Tempo's are designed to make the body more effective at using the aerobic energy pathway meaning that we are able to sustain paces for longer at comfortable effort. The trick is that tempo's do this by tethering on the edge. Run these too hard and you are producing more lactate that your body can clear and as a result your body just gets used to the lactate rather than becoming more efficient at clearing it.

The only time I ever really suffer from lactic burn is after 800m/1500m/miles races. Usually starts a minute or two after the race and can last for a good while, god it's a terrible feeling. I remember myself and Myles both lying at the side of the indoor track in Athlone earlier this year after a nasty 1500m, both of us flooded with lactate! :pac:

Have done some faster sessions in between and the 20:06 yesterday felt much more controlled, less effort and felt a lot stronger. As an aside, I'll be gunning for that PB come Jingle Bells
