The '''Ottawa Race Weekend''' (also known as '''Tamarack Ottawa Race Weekend''' for sponsorship reasons) is an annual weekend of [[road running]] events held the last weekend of May in the city of [[Ottawa]], [[Ontario]], [[Canada]].  The two-day running event includes seven races, including the '''Ottawa Marathon<!-- term currently redirects to this article -->''', all of which start and end at [[Ottawa City Hall]].{{r|event.schedule}}  The [[marathon]] was first held in 1975, and is categorized as an [[World Athletics Label Road Races|Elite Label Road Race]] by [[World Athletics]].{{r|ARRS}}<ref>{{cite web |title=World Athletics Label Road Races |url=https://worldathletics.org/competitions/world-athletics-label-road-races/calendar-results |website=World Athletics |publisher=World Athletics |access-date=10 July 2023}}</ref>  Over 40,000 participants take part in the races each year.

The Ottawa Race Weekend also includes Canada's largest health and fitness expo, which opens on the Thursday before the weekend.  In addition, each year, participants in the Ottawa Race Weekend raise close to $1 million for approximately 25 local and national charities affiliated with the event.

== Races ==

The race weekend includes seven races: a 1.2&nbsp;km kids marathon, 2K, 5K, 10K, [[half marathon]], wheelchair marathon, and [[marathon]].<ref name="event.schedule">[http://www.runottawa.ca/weekend/event-schedule Race Weekend Event Schedule]. Run Ottawa. Retrieved on 2012-06-04.</ref>  All of the races start and finish at [[Ottawa City Hall]].{{r|event.schedule}}

The signature event of the weekend is the Ottawa Marathon, which was first held in 1975. Today it is the largest marathon event in Canada and is a qualifier for the [[Boston Marathon]]. The event is also home to the [[Canadian Marathon Championships]] and the Canadian Forces Marathon Championships.

In 2014 the 10k became the first IAAF Gold Label road race in Canada.<ref>{{cite press release |author=<!--Staff writer(s); no by-line.--> |title=The Ottawa 10K gets the gold! |url=http://www.runottawa.ca/news-item/ottawa-10k-gets-gold/ |location=Ottawa, Ontario |publisher=Run Ottawa |date=November 4, 2014 }}/</ref><ref>{{cite news |last=Robb |first=Peter |date=May 20, 2015 |title=Tamarack Ottawa Race Weekend 10K gets a golden label |url=https://ottawacitizen.com/sports/local-sports/tamarack-ottawa-race-weekend-10k-gets-a-golden-label |newspaper=Ottawa Citizen |access-date=April 12, 2016}}</ref> On October 22, 2015, the Marathon also became an IAAF Gold Label road race.<ref>{{cite press release |author=<!--Staff writer(s); no by-line.--> |title=Scotiabank Ottawa Marathon awarded prestigious IAAF Gold standard |url=http://www.runottawa.ca/news-item/scotiabank-ottawa-marathon-awarded-prestigious-iaaf-gold-standard/ |location=Ottawa, Ontario |publisher=Run Ottawa |date=October 22, 2015 |access-date=April 12, 2016}}/</ref><ref>{{cite news |last=Holder |first=Gord |date=October 22, 2015 |title=Ottawa Race Weekend marathon gets a golden glow |url=https://ottawacitizen.com/sports/local-sports/ottawa-race-weekend-marathon-gets-a-golden-glow |newspaper=Ottawa Citizen |access-date=April 12, 2016}}</ref> In 2023, the race was reclassified by World Athletics as an Elite road race (one level below Gold).
