The South Mesa loop is considered a moderate road cycling experience. While the surfaces are well-paved, the route involves approximately 714 meters (2,329 feet) of elevation gain over 50.9 km (31.6 miles). Additionally, Los Alamos is situated at an elevation of around 7,400 feet, meaning the air is thinner, which can add to the challenge for some riders. It's best suited for cyclists with good fitness levels.

The best time to cycle the South Mesa loop is generally during the spring, summer, and fall months when the weather is most favorable. Summers can be warm, but the elevation often provides cooler temperatures than lower-lying areas. Winters can bring snow and icy conditions, making road cycling less ideal. Always check the local weather forecast before heading out.
As a road cycling route, the South Mesa loop primarily uses public roads. Generally, dogs are allowed on leash in public areas, but specific regulations may apply if the route passes through certain park or protected areas.
