You'll encounter significant ascents and descents, including hilly and mountainous sections around Mynydd Llangynidr. Surfaces can be mixed, ranging from mostly paved roads around Talybont Reservoir to single-lane roads with grassy centers and potential gravel sections. Wider, more durable tires are advisable.
