A great introductory course for the HK50 series as this first 24km of 50km category is not high in elevation and rolling flat areas along the HK trail (Hong Kong Trail with small additional loop around Mt Bennet) to make up lots of kilometers and not terribly difficult until you hit the 2nd half with lots of short steep climbs going around Mt Parker, then the fun starts with Mt Butler, Jardines Lookout and Violet Hill to add to the fun and pain. The course for the 24km category is same on the HK trail as the first 24km of the 50km category.
港島50為香港50越野跑系列賽的入門比賽，50公里組別的首24公里爬升不多及以平路為主，難度不高，在比賽的後半，及至柏架山、畢拿山、渣甸山及紫羅蘭山，有不少短距離的高爬升，為參加者帶來樂趣及痛苦。24公里組別的路線與50公里組別的首24公里相同。
