I think they said 20 minutes. A pro cyclist will probably average 400 watts (and peak and 1200 - 1500 watts sprinting).
For a hill climb, a sustained 100-200 watts over 10-20 minutes will give a distinct advantage. 1s7p should get you that for 20 minutes at 24 volts. Just need to find room for 7 batteries in your frame. I know several people who have put more than that into a steel bike frame.
