About this event
The Guzzler Ultra Trail Running Festival is a challenging multi-distance trail-running event through Brisbane’s spectacular bushland around Mount Coot-tha and D’Aguilar National Park. Presented by NatuRace and supported by the local trail-running community, the festival combines technical trails, substantial elevation and a welcoming checkpoint atmosphere.
The headline Guzzler Ultra covers 105 kilometres with more than 4,618 metres of elevation gain. The course starts at Mount Coot-tha and links Brisbane’s historic reservoirs in the order they were built: Enoggera, Gold Creek and Lake Manchester. Runners have up to 28 hours to complete the course, with the event starting at 6.30 am on Saturday, 17 July 2027. The 100-kilometre event is recognised as a UTMB World Series qualifier and a Western States qualifier.
Those seeking a shorter challenge can choose from several distances:
- The Guzzler Ultra: 105 kilometres, more than 4,618 metres of elevation gain and three reservoirs visited.
- The Glass Half Full: 52 kilometres, more than 2,102 metres of elevation gain and two reservoirs visited, with a 12-hour time limit. This event takes place on Saturday, 17 July 2027, and is a UTMB World Series and Six Foot Track Marathon qualifier.
- The Big Sipper: 21 kilometres, more than 711 metres of elevation gain and one reservoir visited, with a four-hour time limit. This event takes place on Sunday, 18 July 2027.
- The Dry Run: 10 kilometres, more than 399 metres of elevation gain and a three-and-a-half-hour time limit. This event takes place on Sunday, 18 July 2027.
Ultramarathon competitors are supported by a network of checkpoints offering water, fruit, savoury snacks, confectionery, cola, baked goods and, at selected locations, hot noodles, tea and coffee. The longer course also includes drop-bag and crew-support opportunities at designated checkpoints, helping runners manage the demands of a day-and-night adventure.
With distances for experienced ultrarunners, aspiring trail athletes and newcomers alike, The Guzzler offers an immersive way to explore Brisbane’s urban bushland beyond the bitumen. Entries are limited and the event is known to sell out quickly, so early registration is recommended.
