2026 TCS Toronto Waterfront Marathon

The TCS Toronto Waterfront Marathon is a road marathon held in Toronto, Ontario, Canada, during October. It is a full 42.2 km marathon, distinct from shorter city runs, and its character is closely linked to Toronto’s waterfront and downtown running events. The available information does not provide a detailed street-by-street course map, but it highlights a substantial charity program associated with the race. The fundraising goal is CA$2 million, supported by numerous participating organizations. These include Action Against Hunger Canada, ALS Society of Canada, Alzheimer Society of Toronto, Big Brothers Big Sisters of Toronto, CAMH Foundation, Daily Bread Food Bank, Diabetes Canada, Doctors Without Borders Canada, and various other groups focused on disease, disability, food security, children's welfare, and community support.

2026 Women's Training Program

Hamilton Marathon Road2Hope

The Hamilton Marathon Road2Hope takes place in Hamilton, Ontario, approximately forty minutes from Toronto. All activities are centered at Confederation Park on Van Wagner's Beach Road. The event includes a full marathon, half marathon, 10K, 5K, an elite 5K, and a 1K kids run. Shorter races and family walk/runs occur on Saturday, with the half and full marathons on Sunday. This late-fall event's full marathon is a Boston qualifier known for fast times. The marathon and half marathon participants are transported to the start at ArcelorMittal Dofasco Park. All races conclude at Confederation Park, close to the Lake Ontario shoreline. The course features cool-weather conditions, rural sections, and waterfront segments, attracting participants from beyond the local area, as well as area families. A yearly tradition is the Hammer Challenge, requiring runners to finish the 5K, the 10K, and either the half or full marathon.

2026 Hamilton Marathon Road2Hope

The Hamilton Marathon Road2Hope is an annual race weekend in Hamilton, Ontario, Canada, held on the last weekend of October. It features a full marathon and half marathon, alongside 10K and 5K races and a kids race, catering to experienced marathoners, casual runners, families, and first-time racers. The marathon is scheduled for Saturday morning, and the half marathon for Sunday morning, allowing each headline race its own day. While specific route details are not provided, the race's focus on local charity fundraising is evident. Participants can raise funds for organizations such as CityKidz, Hamilton General Hospital, Hamilton Health Sciences Foundation, McMaster Children's Hospital, YWCA Hamilton, the Canadian Cancer Society, Hamilton Literacy Council, and various youth, health, and community groups.

Conwy Half Marathon

The Conwy Half Marathon begins and ends on the quayside, directly in front of the historic Conwy Castle, which is over 700 years old. This road half marathon takes place in North Wales during November. A fun run is also part of the event, and the race has a maximum capacity of 4,000 participants. In recent years, over 3,000 runners have taken part, giving it the feel of a large-scale event rather than a small, local race. The course departs Conwy along the Conwy River, proceeding towards Deganwy and the West Shore in Llandudno. It then follows Church Walks towards Llandudno Pier. From the pier, the route encircles the Great Orme, offering expansive vistas of Anglesey, Puffin Island, and the North Wales coastline, before making its way back to Conwy. Readers of Runner's World recognized it as one of the top five half marathons in the UK for its scenery, and the course has a history of facilitating numerous personal bests.

2027 Chilly Half Marathon

2027 Beneva Mississauga Marathon

The Beneva Mississauga Marathon takes place in Mississauga each spring, offering a full marathon, half marathon, 10K, and 5K. The marathon course is known for its speed, qualifying runners for Boston, and appeals to those aiming for a standard as well as participants seeking a shorter city race. With over twenty years of history, the event emphasizes health, commitment, and community, extending beyond just the marathon distance. The course winds through Mississauga's core, featuring the city centre, the Credit River environs, and the University of Toronto campus. An official app allows spectators to send Cheer Zone messages and track participants in real-time. Runners can access course maps, race information, and updates within the same application. The variety of distances unites marathoners, half marathoners, 10K and 5K runners, families, and local spectators for a shared race weekend.

The ThermoFisher Scientific Grand Island 1/2 Marathon

The 32nd Annual Buffalo tradition offers a quality running experience and gives back to the community. The flat, out-and-back course runs along the Niagara River, mostly closed to traffic, with no time limit. First-time half marathoners receive a special medal and photo op. Every finisher of The ThermoFisher Scientific Grand Island 1/2 Marathon gets a commemorative race shirt and medal. A post-race party, free live tracking, and downloadable photos are included.

About Half Marathon races in St. Catharines-Niagara

St. Catharines-Niagara Training Notes

St. Catharines-Niagara hosts 13 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals run Merritt Trail, Terry Fox Trail, Waterfront Trail, Seaway Haulage Road, George Nicholson Trail, Walker's Creek Trail, and The Twelve Trail East when they want steady base miles without overthinking it. The trail covers 6 miles of gravel and paved sections, and the north section stays popular with pedestrians. St. Catharines Roadrunners and Walkers meet Wednesday at 6:30pm at Cat's Caboose, then roll into Saturday coffee runs and Sunday morning trail runs at 9am. The Don McMaster Memorial 12 Mile Creek Trail Half Marathon & 7k, Run for the Grapes Half Marathon & 5K, and Welland Run 10K work as anchor events.

Locals ride the canal trail, Merritt trail, waterfront trail, Walkers Creek, Grantham rail trail, Welland Canal, and Lakeshore when they want Z2, intervals, or a longer gran fondo day. Welland Canal is the clean bet for a decent ride, and the path takes about 30-45 minutes one way on a road bike. St. Catharines Cycling Club brings the fast crowd with Tuesday fast training, Time Trials, Saturday training rides, Sunday training rides, and a Wednesday Women's Group. Amici per la Vita also pulls Niagara riders together. The 3 km paved loop from St. Catharines carries 346 m of gain, so the climbs are rolling, not mountain stuff. Catharines has 346 m of elevation gain, so the climbs are rolling rather than steep.

Summer gives the clearest calendar pulse, with the Canaqua Sports Mid-Summer Classic - Welland on August 2, 2026 and the Welland Canal Open Water Swim on August 30, 2026. Locals keep the canal, Waterfront Trail, and stone dust trail options in the rotation when legs need volume and the day is built for base miles. Winter changes the feel more than the map, because paved sections, gravel stone dust trail, and club meetups matter more when conditions tighten up. Runners still use the short loops and trail runs, and cyclists keep the Z2 honest when the road bike days get selective.
