My shoes melted due to heat: 52-year-old woman who ran 1,000 km in 12 days

Ultramarathoner Natalie Dau recently completed running 1,000 km across Thailand, Malaysia and Singapore in 12 days. The 52-year-old ran the equivalent of two marathons, or 84 km, per day and said her shoes melted due to 35°C heat. Dau finished her solo run despite facing a hip injury on day one and contracting urinary tract infection on day three.
