Interesting experience to say the least. I am training for 3 miles in just under 18 minutes. The most I have ever ran/jogged in my life has been one mile. My best 1 mile time has been like 10:30 in junior high . I did my first mile in 9'40. That alone was a personal record.. so my gf and I ran that mile with her timing me then we walked 800m as a cooldown. Then she forced me to run another mile. By the 3rd lap (4 laps = mile on this track) I was dead. Everything hurt. Legs, lungs, head etc. On my final lap, I was complaining and bitching out and just coming to a dead stop every 75m or so. Everytime I stopped my girlfriend got behind me and started shoving me hard as fuck. She ended up shoving me 5-6 times and calling me a little bitch and referencing how a girl was easily out running me . She would not let me quit no matter what. Which brings me to the point of this thread: I guess I have never really experienced what it is like to be truly mentally tough. Last night I received the tiniest of samples of what it will be like to be of sound metal toughness. Hitting that minor wall of feeling like death and pushing through it (ie forced to but regardless) was a shock and a mind expanding experience. It only shows me that I have never really pushed very hard physically in life in the weight room or on the track. Running and cross country crew already know infinitely more about this than I do but for those that never get out and run on a regular basis, do it. side note: what is proper breathing technique for running long distances ? How should my arms chest legs and head be held while running? Any other pointers? I am going to get 3 miles in under 18 minutes but I want to be able to put away 5-6 miles in a session.
