If you are a weekend warrior, you could very well be in shape for this trip, but you might want to specifically train for a few months on a more regular schedule. If you do spin classes at your gym but rarely get on a bike on the trail, you might want to try a long weekend trip to test your legs. In any case, call us to discuss the details - we can help you evaluate your ability. The typical day in the everest region includes a pretty full day of cycling at very high altitudes. While many experienced cyclists will have no problem with the distances and even the elevation changes, the factors that are most relevant are the actual altitude and the road conditions.
Some segments are on quality pavement, but much is on varying types of dirt roads.
While this is nothing like single-track Mountain Biking, it definitely slows us down and makes for intense peddling. The altitude is an issue over which we have no control, no matter how much we train. Different people are affected different ways. Even the strongest athletes can be wiped out by thin air. You only preparation is to train at high altitude.
