If you are an active, healthy person who exercises on a regular basis and has a love for mountains and biking, then this is the trip for you.

All the nights on this trip are spent in a tent, so it also helps if you like camping!


A lot the trip is above 1700 meters in altitude. The highest pass we cross is 3500 meters. The air is noticeably thinner higher up and depending on the individual, effects can make an appearance on from 2000m onwards. This may be as minor as a mild headache, feeling a bit lethargic and shortness of breath after physical exertion. However, it is very important to acclimatise slowly to give the body a chance to adapt to the change of conditions. We have designed the itinerary with this in mind. Feel free to discuss this with our team or consult with your doctor. Adequate hydration is also very important and the advice is that you need to be drinking at least 4 litres a day on the tour.

Health and Hygiene

It pays to be vigilant around food and with personal hygiene to avoid illness or upset stomachs - both on tour and leading up to the tour. Keep some hand sanitiser and wipes in your day pack. Consult with a travel health clinic at least a month before travelling to see if you require any vaccinations.

This is a camping trip staying in a variety of campsites near the best riding on offer in Colorado. Twin share with someone of the same gender. Your own tent can be requested at an extra single supplement charge of US$150. Contact us if you would like us to book your pre-night's accommodation in Denver. We recommend the Mile High House, 1445 High St, Denver.

Local mountain bike guides

Our on the ground trip leaders provide support and will focus on the details so we don't have to. The trip will have two/three leaders for the group. Not only have they guided thousands of miles on bikes but are excellent at cooking healthy and hearty meals and are there to help during camp set up. Top priority is health and safety for all our guests as well as as showing you a good time. Past clients love our leaders and give them a 97% rating for all round quality service. 


What will the climate be like in Colorado in September?

We picked mid-September as the Autumn (Fall) colours are spectacular and the weather is settled. The nights can be cooler though and the temperature can fall as low as 1-5°C at the camps. During the day it can get up to 25°C but more often around 15-20°C. Clothing layers will be the key as the altitude differences experienced in a single day can expose you to a big temperature range.
