Hannah Nicklin decided that, during her thirtieth year, she would complete an Ironman triathlon event. There can’t be many people who are interested in completing a 2.4 mile swim, 112 mile bike ride and a 26.2 mile run all in one go. But ‘Equations for a Moving Body’ is a look at the people who do, the people who train them, the people who support and inspire them. This solo show sees Nicklin use projected live internet pages like a PowerPoint presentation. She’s an engaging performer, speaking passionately about something which she clearly cares a lot about. This makes ‘Equations for a Moving Body’ a delightful show, and not just for those interested in triathlons.

Northern Stage at Summerhall, until 27 Aug.
