In the end, it wasn’t even close. After seven minutes of searing pain, during which Sanita Puspure had to go to a deep, dark place to overhaul Emma Twigg of New Zealand, the 36-year-old crossed the line with room to spare. Puspure’s victory in the single sculls in Ottensheim, Austria meant she retained her world title, an astonishing feat after a hard year, during which she lost her sister to cancer. But the Latvian-born rower is made of such resolute fabric that her mind never faltered from her final destination: the top of the medal rostrum. The world’s best, yet again.
