Trailblazers were formed in 2018 to take part in the inaugural Women's T20 Challenge competition, in which they played a one-off match against Supernovas.

[1] Indian batter Smriti Mandhana was named as captain of the side, alongside fellow Indians Deepti Sharma and Jhulan Goswami as well as overseas players Alyssa Healy, Suzie Bates, Beth Mooney, Danielle Hazell and Lea Tahuhu.

Supernovas batter Ellyse Perry hit a single off the final ball to crown her side champions.

[9] Trailblazers played Velocity in their first game, bowling them out for just 47, with overseas bowler Sophie Ecclestone taking 4 wickets for 9 runs.

Velocity were restricted to 174/9 in reply, but the group ended with all sides on two points, with the Trailblazers on the worst Net Run Rate, therefore being eliminated from the tournament.
