The Double Or Nothing Test for Katherine Legge Katherine Legge's bid to complete the "double" – a one day, two race marathon at the Indianapolis 500 and Coca Cola 600 – is an experiment in endurance, planning, and adaptability under pressure.
This historic attempt will test her driving skills as well as her ability to execute a complex strategy.
Unlike previous drivers who attempted the double, Legge has mere days to fine tune her plan, instead of weeks or months.
