instead of running 4 miles straight, would running 2 miles in the morning and 2 miles in the middle of the day have the same effect as running 4 miles straight? stamina wise,fat burn etc..

It would probably be more inconveniant to do 2 different runs, imo a 4 miler on its own would improve your stamina more as you are not resting and doing it straight

if i was you ido all my exercise at the same time

2 miles is long enough for amateur conditioning. Running 4 will only make the intensity lower. Therefore doing 2 miles twice, with higher intensity (you can run 2 miles at a higher pace than 4 miles) will burn more calories and be better for (amateur) boxing conditioning.

just on it on 5mph on the higest incline for 3 miles thats a good jog/run for amature

I do my 4 mile run at the same pace as my 2 miler

I do my 4 mile run at the same pace as my 2 miler

Then you're not going fast enough on your 2 miler ;)

I agree with punch drunk, about how long does it take you to run 2 miles?

It's really simple, and anyone who's ever tried to run 2 miles and 4 miles would know this; The longer the distance, the slower you'll run.

makes sense..i thought for sure 2 miles twice wouldnt b as effective as running 4..thanks for the help

i run 2 minute intervals as fast as i can with one minute rest in between to mimic the work to rest ratio. do about 6 "rounds" of these. i'll go on the occasional 4-5 mile run 2 days or so a week, but the other days are 2 minute intervals with one minute rest, 1 minute intervals with 30 sec rest, 200 meter sprints, 100 meter sprints, sprinting backwards. i always like to incorporate different things to shock the ol' body.

mayb i was exaggerating but I can do my 4 miler in around 26 minutes which is around 6 1/2 minute miles and that means running a 2 miler in 13 minutes
