Hi all, last night I did a track session of 16 x 400 metre runs with each run starting every 2:05. My average 400metre run was completed in 1:23, leaving 42 seconds to get my breath before starting the next one.
A week ago I ran 8 x 800metres, similar principle with a new run starting every 4:00 and average speed of 3:00 leaving 60 seconds to recover.
My current PB's are 5k 19:22 and 10k 40:57 and I found both sessions tough.
My question is, what exactly does this training do to improve my performance from a physiological perspective? I realise that it teaches my body to move my legs quicker, but with so much information about lactate thresholds, tempo runs, intervals, anaerobic/aerobic conditioning I have been overwhelmed with information that I am struggling to make sense of in my mind as I have been running for only a few months.
I undestand they will be beneficial but I would like to know how exactly instead of just turning upto a track and running them oblivious of the effect.
