Back down the disused railway line for my long slow run this morning. Decided to stretch it out to 7K after a comfortable 6K on the same route previously. Ran at the top end of the aerobic zone on my watch (zone 3 yellow) and to keep it there it's really no more than a gentle jog. Body is working aerobically here so plenty of oxygen in to fuel the muscles and plenty of carbon dioxide out to rid the body of toxins. No lactate build up here hence no "Toxic 10" or Toxic 7K for that matterπ
All in all a pleasant run, had time to look around and time to concentrate on my running form. This is the "easy conversational pace" that we hear so much about and at the end was hardly drawing breath. What I have noticed is an ache across my upper back and shoulders and am hoping this is because I'm trying to hold myself better rather than my usual slouch!!π
