Smeags on 22 March 2011
The hardest time I had with a Gym Leader was the 3rd leader (Castelia City), who has bug Pokemon. It was that darn Leavanny of his (Bug/Grass) that tore through my entire team. Doesn't help that my team was Dewott, Zorua, Drilbur and Cottonee... who were all weak against his attacks. 
After my humbling battle, all it took was a Darumaka's Fire Punch to bring him down though.
