🏳️ Mary Riddel

Mary Riddel raced in amateur-level multiclass sprint racing in the United States between 2012 and 2015. She drove Porsche 944s, primarily in NASA's 944 Spec class and PCA Club Racing's SP1 class, fielded by teams running the same machinery across a broad amateur and semi-professional grid.[1]

Her record spanned 24 starts across both series. She took one win and one podium in PCA Club Racing during 2012–2013, finishing 15th in the season standings. Her NASA tenure, from 2014 to 2015, produced 19 starts without a podium finish. She finished behind regular rivals Simon Peck and Jim Hicks consistently throughout her time racing, though she defeated semi-professional driver Daniel Williams once and club-level driver Charles Sharp once across her career.[2]

Riddel raced in fields where the grid mixed amateurs with semi-professionals and graded professionals, though she typically finished outside the points against most competition. Her single victory came in a one-make class, where she demonstrated she could win against her peer group; her broader record against the regular amateur and semi-professional opposition she faced most often showed her racing at a developmental level within that amateur field.
