The course crosses the Weston coastline via closed roads, incorporates a segment on the beach, and passes through a nature reserve. Participants are treated to open sea views before reaching the pier for the finish. The event utilizes chip timing, retains historical results, and attracts charity runners, such as those fundraising for the Great Western Air Ambulance Charity with their "Make your seconds count" initiative.

The Cardiff Taff Trail Half Marathon begins at Pontcanna Fields Car Park, directing runners into one of Cardiff’s primary green spaces. This chip-timed half marathon features online entry, an 08:30 start, and race-number collection prior to the start. With a 3-hour cutoff, it is structured as an efficient city race, not an extended trail excursion. The course crosses Pontcanna Fields and Bute Park before proceeding north on the Taff Trail towards Tongwynlais. The majority of the route follows tarmac paths, with a brief compacted section. Aid stations are located at approximately 2.5, 6.25, and 10.25 miles. The event originated as a pilot and resumed post-Covid cancellations, offering Cardiff a smaller Taff Trail half to complement the city's larger October road race.

MoRun Cardiff is a Movember running event held at Coopers Field in Bute Park, near the city end and central Cardiff. It features four distances on the same morning: a Half Marathon, 10k, 5k, and a 1.5k Mini MoRun for children and families. The Half Marathon begins first, followed by the 5k and 10k, with the Mini MoRun later. Registration opens early, race numbers and timing chips are collected on site, and all distances are chip timed with instant results at the finish. The route follows the paths of Bute Park, with runners grouped by estimated finish time and staggered at the start to prevent path congestion. The field is broad: half marathon runners, 10k and 5k runners, children, families, friends, first-timers, fundraisers, and those attending for the Movember spirit. Fancy dress is part of the day, and participants are encouraged to grow a moustache or paint one on. Every finisher receives a MoRun medal and headband, with additional prizes for fastest MoBro, fastest MoSista, best dressed, and best Mo. The event supports Movember, raising money and awareness for prostate cancer, testicular cancer, mental health, and suicide prevention.

Races begin in the morning, and chip timing is used for all distances, including the children's Mini MoRun, providing runners with immediate results. The atmosphere is intentionally festive, with a clear structure: choose a short family-friendly run, a standard 5k or 10k, or the full 21.0975 km half marathon. The courses cover Cardiff city grounds and public park areas. The 5k, 10k, and half marathon are each designed as single-loop routes. This event is part of the larger MoRunning series supporting Movember, which raises funds and awareness for men's health issues such as prostate cancer, testicular cancer, mental health, and suicide prevention. Participants can donate during registration or create a fundraising page. All MoRunners receive a medal and a MoRunning headband.

Trail Revolution Margam Trail Races are November trail runs in Margam Park, with 5km, 10km, and half marathon options. The setting is parkland and forest rather than road, and the routes use undulating trails that make the event more about handling changing ground than chasing a flat fast time. The half marathon starts first in the morning, followed by the 10km and then the 5km, so runners can choose anything from a short forest race to a longer test around Margam. The event sits under the Trail Revolution banner and is aimed at runners who want hills, woodland, and a tougher surface underfoot.

The series supports Movember, raising awareness and funds for prostate cancer, testicular cancer, mental health, and suicide prevention. Participants can donate during registration or create a fundraising page via Movember or JustGiving. All finishers receive a MoRun medal and headband, with refreshments available at the finish line. Additional prizes are awarded for categories including fastest MoBro, fastest MoSista, best dressed, and best moustache.

The Machen Trail Half Marathon & Marathon are trail races near Machen, South Wales, covering approximately 14 and 26 miles respectively. The courses traverse woodland, common land, open moorland, streams, ridgeway paths, steep ascents, and fast descents, offering a challenging off-road experience distinct from road races. The half marathon course is fully marked, whereas marathon participants are responsible for navigation, with marshals present at key intersections. All participants must pass a mandatory kit check at registration; those without the required equipment will not be permitted to start. The half marathon begins in Machen, proceeding through single-track trails to Rudry Common, then into Caerphilly Forest before descending to Cefn Onn. A sustained climb leads runners back to the ridgeway, passing the Lisvane / Llysfaen trig point. The route continues through woodland towards Ruperra Castle, descends into Draethen, climbs into Machen Woods, and concludes on a downhill trail. Marathon runners cover this route and then face a significant climb towards the Rhymney Valley and the summit of Machen. This event is suited for trail runners who appreciate technical woodland paths, exposed ridges, winter kit requirements, and climbs that make the descents rewarding. Medals are awarded to all finishers, with trophies for top performers.
