Lael Wilcox has started her round-the-world record attempt, riding 282 miles (454km) on day one. Wilcox holds the women's world record for circumnavigating the globe by bike, covering 29,169km (18,125 miles) in 108 days, 12 hours and 12 minutes in 2024, beating Jenny Graham's previous record of 124 days. Now Wilcox has her sights set on breaking Mark Beaumont's overall record of 78 days, 14 hours and 40 minutes, established in 2017. Wilcox set out from Buckingham Fountain in Chicago, Illinois, at 4am on Sunday (June 7) and plans to finish before 6.40pm on August 24. She's planning to average 231 miles (372km) per day across the whole journey, but will aim to cover 240 miles (386km) for each day on the bike, to account for transfers. She's riding with the backing of a support crew (an Instagram post describes how lasagne and meatballs "hit the spot" at her first break, after 175 miles). Wilcox's day one route took her from Chicago to Kleinke Park, passing through three states along the way (Illinois, Wisconsin and Michigan). At the time of writing, Wilcox is back on the road for day two, heading towards the Canadian border, now with 353 miles (568km) under her belt, at an average moving speed of 18.8mph (30.3kmh). She has 17,749 miles to go (28,565km) on a route that will see the 39-year-old cover four continents.

To qualify for the round-the-world record, riders must: Ride a minimum of 18,000 miles in one direction Start and finish at the same location Traverse at least two antipodal points (locations on exact opposite sides of the Earth) "I'm having such a good day," said Wilcox on her daily podcast, recorded on the bike with 20 miles to go on day one. It's mesmeric listening, with only the whir of Wilcox's tyres and cassette for company. "Conditions have been pretty good: great weather, a little bit of head-crosswind, but otherwise really beautiful," she added. Wilcox describes how she woke at 2am before being met by "more than 100 people waiting in the dark with their bikes to see me off", many of whom rode significant parts of the day's route with her. A similar number of well-wishers greeted Wilcox in Kleinke Park. "I could have cried, to be received by that," she said.
