Wouldn't training to raise AT reduce time above AT on subsequent rides? But if you want to delay fatigue to the greatest extent and pace can be self-selected (rather than dictated by a time limit or keeping up with a group) then the best approach would probably be to limit intensity to below the point where blood lactate begins to rise above baseline.
