Dumbasses arguing about running.

[CFH]

Stop being fags, fuck the treadmill, 45 minute run with 3-4 sets of hill sprints will shed fat and build more fitness than some drawn out plad ever will! Unless you've got weak joints you've no excuse.

Whilst I enjoy running distance (some what,i fucking love to sprint!) it's not the most effecient way to run unless your goals are just marathon type endurance. If it comes down to fat loss and Aerobic/Anaerobic thresholds and recovery rates ('conditioning') then slow, long duration training is quite literally a long road to no where.

It gives minimal metabolism boost and only really works one energy system.

You do need a good Aerobic base, but you should quickly progress on from there.

And as for 12.5 miles in 3 hours, I'm not a distance runner and I xan run 13.3 miles in about 1 hour 30. Don't know about with a 15kg pack... I'd imagine I'd be fastet than 3hrs though... You'll ve fine with a bit of training.

On the cross trainer I run

Does not compute!

What about a longish run (ie 8-11km) with numerous large hills mixed in (like hills that leave you gasping for breath when you reach the top)? That's something I do fairly regularly.
