Course intel
Welsh coastal loop from Tenby: the climbs are not long but they almost never stop, close to 2000 m of elevation gain paired with September sea wind and showers, on narrow roads with many bends. It takes more out of you than the numbers suggest, so a slightly conservative IF is the safer plan.
