Nope. Need to re-think that. Lift only has to overcome the weight. The issue is the application of rudder, which might require more thrust.

The real problem with a runway like this is that you want to take-off and land against the wind. Going in a circle you could rapidly gain or lose effective lift as your angle to the wind changes.
