Grouse Grind

I wasn't able to attend the grouse grind field trip due to an injury, but I remember the previous time I went up the grouse grind which was 8 months prior to our field trip. I remember my inability to stay at a steady pace due to the build up of lactic acid. There was this burning sensation which was there continuously through out the whole 42 minute climb for me. My quadriceps, hamstrings, calves and shins. My heart rate and and breathing ratw varied depending on thr climb. For the most part it was steady, but on a certain inclines they both dramatically increased at the same time. My body temperate was probably at its highest point that it's ever been in my entire life, you were able to see the red blood vessels popping out of my skin. Glycolysis and aerobic system are the two metabolic systems being used in this physical activity. The grouse grind is a short walk which is less then 70-75% of your effort and lasts for about 30 seconds to a minute with short breaks In between each walk up the inclined hill.
