Assuming that long-distance, non-competitive bicycle riding is a sport to which the primary assumption of the risk doctrine applies, the County owed the cyclist a duty not to increase the inherent risks of that sports by failing to properly maintain its roads on which the cyclist traveled. Imposing such a duty on the County would not significantly increase its burdens since it already owed a duty of care to other, non-sports users of the road. Here, the County breached its duty by failing to fix a four-foot by three-foot pothole that was four inches deep and posed a risk to any user of the road. The County was informed of the pothole six weeks before plaintiff’s accident but had done nothing to repair the road.
