Now in its 6th year, DirtyClean Challenges are authentic, stunning and tough gran fondo type races. Participants compete on time segments, on open roads, and races are supported en route with drinks, food, and tools. We have a loyal following of riders who join each year, not just to complete but to be social, make new friends and have a great weekend centred around cycling.

Q&A 2025

2025年的挑战有很多的改变

> DC 挑战赛和普通比赛有什么区别！ = 主要区别在于挑战从开始到结束没有计时。我们有4到8个计时段，不包括下坡。这使得活动更安全，也更具社交性。你需要使用 GPS 记录你的骑行并将其上传到 Strava。

> How hard is a DirtyClean? = you should be able to ride for 3h to 5h over hills. You should be confident in descending hills. Don’t do a DirtyClean if you are not good with your brakes. Come to one of our learning weekends for that.

> What are road conditions like? = the same as what you would encounter cycling around Shanghai or Hangzhou or anywhere else. Mostly good condition tarmac and concrete roads. In some small places, you might encounter minor road cracks, rocks or issues. We minimise these and try and get the government to clean the roads before an event.

> How steep does it get? = Please check the route files. We will warn you if they are steep. Some are!

> What tires do you suggest? = given modern day wheels and tires, we would suggest 32’s and nothing less than 28s. Tubless or proper innertubes, no rubbish TPU please.

> What gears do you suggest? = standard road bike or gravel gearing. We would suggest 1to1 gear ratio but many strong riders enjoy their time on a normal compact or standard road bike ratios.

> What happens if rain is forecast or there is heavy rain at the start? = we will check the forecast on Thursday PM before the race. If heavy rain for most of the delay is forecasted, we will delay or cancel the event. If very light showers are forecasted or near the time of the start, we will go ahead, probably on a different “backup rain course”.

> What happens if it has been raining a lot recently? = it can be sunny but water still rushes off the mountains down the roads, making them unsafe. We will switch the course to a “backup rain course”.

> 我需要自己修复爆胎吗？ = 是的，或者请伙伴帮助。至少带一个备用内胎，最好带两个。

> What support is provided? = normally, someone can help with minor things the night before the event, but make sure your bike is well serviced before with fresh brakes and tires (good practice for any race). = we have one or two support vans. They have pumps, first aid and basic tools. They provide hot coffee, drinks and carb snacks. Its best to bring a gel or two in case. You should not be more than 20km away from a shop. In case of an issue, we can call in local vans to take you and your bike back (cost depending on where you are).

食宿

If you are unable to find rooms on our booking site please contact our service account and they will help you find somewhere to stay in other local nonjiale and hotels.

The DC events start and finish in a remote village that has easy motorway and high-speed train access. Stay at Wildhomestay or we can help organise rooms in other local hotels or turn up for the event on the day. A BBQ and fun awards ceremony is organised on the night of the event with a free flow of beer, lots of prizes and bonfire banter. Authentic local fondo’s not to be missed!
