Dirty #1 2021-04-24

Dirty #1 – April 24th Weekend

Entry Booking at the bottom of the page.

Description: Small scale adventure ride challenges. A bit of a change for this year. We want to try out a shorter / easier Dirty and the normal bloody hard Dirty on the same day. Please be realistic about what you can do and both are still real challenges. The courses are mostly located on small rough roads with some non paved sections. There will be timed stages which makes for a safer and more social but still highly competitive and fun day out. Support and stopping points provide enroute. Events will be delayed if terrible weather or changes to current covid situation making it unsafe to hold the event. 

Somewhat Dirty Pigs (the easier one)

  • Date: April 24th 2021, 8am.
  • JR’s Intro: A little bit of everything for the less experienced adventure “gravel” rider.  At the end it will leave you wanting to explore more on your bike.  The route takes in the broken concrete of the river out of Sanyang and segment #1, followed by perfect tarmac towards Poshan.  Crossing the river you head up through segment #2 to the first real off road section and segment #3.  Segment #4 takes you to the highest point of the day and the ability to get a great view.  The downhill is fun but be very careful.  When you hit the main road there is segment #5 which rolls back the way you came.  Then relax until segment #6 which is the final stretch back to the homestay. 
  • Time: Depends on your level but assume 3h for fast rider and 6h to 8h for slow rider with some pushing. 
  • Level: Basic with strong fitness. You need to be confident braking downhill. You need stamina to spin uphill for more than an hour! If you’ve  just starting out this is not for you. Come up another time for one of our Tanqi Adventure Riding weekends.
  • Equipment: Gravel, Mountain Bike, Hybrids, Road bike with 32 or wider tires. MTB or flat shoes. If you don’t have a suitable bike we might be able to provide you one through our Tanqi Adventure Riding program with Specalized. Contact us for more info.
  • Segments: #1 Concrete River Out: https://www.strava.com/segments/20341812 . #2 I hope it is not all like this https://www.strava.com/segments/27644846 . #3 Rolling Gravel https://www.strava.com/segments/27644910. #4 To Pig’s Peak https://www.strava.com/segments/27644964. #5 It’s flat all the way now https://www.strava.com/segments/27644882. #6 Wildhomestay YC Finish: the standard one.
  • Route:


Totally Dirty Cork (the harder one)

    • Date: April 24th 2021, 8am. 
    • Route: Frozen Cork & Black Hills. 86km with two main climbs and lots of other small ones. 2 sections of off road. 1900m. 
    • Time: Depends on your fitness but assume 4h+ for fast rider.

    • Equipment: Gravel or Mountain Bikes only. 
    • Segments: Being expanded.
    • Route: Dirty #1_ Totally Dirty Cork v.2

Further Info

Please understand these rides are not professional races but small scale amateur cycling challenges. To maximize social fun and minimize stupid behaviour points are given for various challenging segments. The rest of the day is meant to be spent riding and chatting in groups. Cool refreshments provided on-route along with a few fun awards. Please be realistic, these are not aimed at the beginner and are demanding, in amazing but challenging landscapes.

If we have serious weather or health warnings it will be delayed. Sunday will be a social ride.
