Here's a way to make it a little little bit more entertaining.
1. Get on the treadmill at a slow pace. Make sure the settings show kms, not miles.
2. Warm up by walking briskly for 2-3 minutes.
3. Now start running SLOWLY at a pace of like 7 (km/h)
4. Now run for a minute at 7, then increase your level by one tenth the next minute, increasing till you get to 8,5 or whatever level is still ok with you but you have to give it some effort. Then go back down again. You do this and you have your 30-minute workout and a slight boredom relief.
I've done it and loved it.
