Women can achieve the Olympic standard in any of three ways:

By beating the World Athletics (formerly IAAF) qualification time (2:29:30 – also known as Olympic standard) in a sanctioned marathon

A top-10 finish at the 2019 World Championships, or in any of the six Abbott World Major Marathons during the qualification period

A top-five finish in a certified World Athletics Gold Label marathon (anywhere in the world – Canadian examples include the Scotiabank Toronto Waterfront Marathon and the Scotiabank Ottawa Marathon).
