I'd like to express my sincere rejection of the 6:30 claim once more.
Going by the record time for 2000m, 2400m would take 5:40. It would obviously be a little longer than that, due to the taking into account the extra endurance.
That's someone who's trained just for that, running in gear designed specifically for the event, on a track designed specifically for the event.
The Paras train to carry large loads, do the run over rocky and hilly terrain, wearing boots designed for anything but fast running. Those alone would almost certainly bring them in at 7 minutes or more, never mind the fact that they are nowhere near the level of olympic athletes.
You're talking rubbish.
The guardian had a series of articles on army training which included a summary table of the times run by service personnel. Apparrently only the top 1% of men under 30 consistently make it in under 8:15.
Treadmill is very easy to run decent times on, 6mins a mile is a lot easier than on a road for example. Continue to do both to maximise your progress, maybe every 3rd run outside to minimise shin and knee impact.
...but it highlights the point that a lot of road running is bad for you. Some, yes as I believe the joints need some stressing to keep cartilage and fluids in good shape but too much will bugger you up.
Which begs the question, how much is too much? When do the long term damages outweigh the benefits? How many miles a week/month before long term damage is likely?

Well Zefan and firstborn i have seen it with my own eyes and also your wrong thinking to get near an olympic athelete by lets see.......
5:45 = WR = 345 secs
45/345 = 13%
Having seen them with my own eyes it wasnt that unreasonable.
Road running being the sole cause of joint damage is unfounded as far as I am aware.
