Cardio and endurance training treadmill routine that workd and fun

Some treadmills will also have built in interval programs (I rarely run on treadmills but used one at a hotel that had a screen and simulated a number of different running courses including trails etc)

To build endurance you should be doing both intervals and steady state workouts (the intervals are probably more fun on a TM)

It is indeed a good workout, and makes time go fast merely for the fact of watching the time.

Indeed look for the interval option on the treadmills - you can usually at least get 2 of the speeds in there and time, then merely add 1 min of the fastest to the jogging interval.
That way you aren't having to hold down a button to increase the pace except on the jog to run portion.

That'll become more important as you are sprinting up a steep hill having trouble even hitting a button with a finger! ;-)

I have been doing my treadmill's pre-programmed intervals for months and I really enjoy it. I guess I started in June, and Thanksgiving I ran a straight 5k on it. Generally though I do 2 mins walk at 3.5, and 3 mins run at 4.5 or above (I push it up depending how I'm feeling). There's a more endurancey one I did last week too which is running at 4.5 again but the walks are at 4 which really keeps you up there. I like it. I also play roller derby so I find the interval training a useful sort of cross training for a sport where I need lots of energy and power for short periods.
