Wooded jungle-edge gravel, tropical heat/humidity, dust. Friday shakeout ride. Only UCI Gravel World Series event in Asia. Our prior 81mi/2,756ft matched the official 130km course — confirmed 2026-07-14.
Signature challenge: The Dustman's real challenge is the climate, not the topography. Its 840 metres of climbing over 130 kilometres never organizes into a defining ascent, but tropical November heat and humidity in the Kanchanaburi river valley tax every effort for four-plus hours. Add jungle-edge gravel that runs dusty in a dry year and greasy in a wet one, and the course rewards riders who pace the opening hour conservatively and treat hydration with the same discipline as their power.
From the Field
There were actually more than 10 river crossings with a lot of mud and I mean a lot. I would actually say this was the hardest gravel race I actually participated in.

I would actually say this was the hardest gravel race I actually participated in but also a very very fun trip.

My legs are shot. My arms are shot. I have nothing in the building. I'm pushing. He's pushing with my hand. Pushing.

Frequently Asked Questions
What is the climate like at UCI Gravel Dustman?
Historical weather data shows average highs of 87°F and lows of 73°F, with a 51% chance of rain on any given day. November in Thailand should offer post-monsoon conditions with manageable heat and humidity, but we have zero historical weather data to confirm this theory. Courses are weather-dependent suggests conditions can turn challenging quickly. Racing in tropical climates is always a gamble - you're either getting perfect shoulder season or getting cooked. Similar climate challenges to SBT GRVL.[2]
How are the logistics for UCI Gravel Dustman?
Bike Zone Events has contact infrastructure in place, but Caroline Livesey's observation that 'there were a lot of people with the wrong tyres for the job' suggests pre-race course condition communication was inadequate. The muddy conditions that made 'slicks a death trap' caught many riders unprepared despite organizers noting routes can change due to weather.[1]
How adventurous is UCI Gravel Dustman?
Racing through ancient Khmer Empire ruins in rural Thailand delivers cultural adventure most gravel races can't touch. Muang Sing Historical Park as start/finish location beats another brewery parking lot by miles. The adventure factor depends entirely on whether they embrace the unique setting or treat it as generic backdrop, and course route changes suggest they might not have fully figured that out yet.[1]
How prestigious is UCI Gravel Dustman?
This is the only UCI Gravel World Series event in all of Asia, which sounds impressive until you realize it's because nobody else wants to deal with the logistics. It's a direct qualifier for the World Championships in Australia, but being the sole representative in a massive continent doesn't automatically make you elite. The UCI rubber stamp is real, but prestige requires more than geographic monopoly. "This is the first time Thailand has been host to a UCI Gravel World Series race, and when the opportunity came up for me to race I couldn't refuse. I'm so glad I came, it's been a special week."[4]
Should I race UCI Gravel Dustman?
If you're serious about Worlds qualification and can handle November heat in Thailand, this is your most exotic path to Nannup. The 130km course through ancient Khmer ruins isn't technically demanding, but weather-dependent route changes and Southeast Asian logistics will test your adaptability more than your FTP. Show up with flexible travel plans and backup gear.
