The 2nd Augusto Manuel Carneiro Pereira Resistência is a stage in the Alenquer Inter-Freguesias mountain bike endurance series, featuring races across various parishes within the Alenquer municipality. Each event follows a straightforward two-hour format: participants complete multiple laps on compact off-road courses, typically ranging from 4 to 7 km, with racing primarily on dirt tracks and narrow trails.
The series welcomes participants aged 16 and up, accommodating both licensed and unlicensed cyclists. It features categories for men, women, e-bikes, and various age brackets, drawing together club athletes, local competitors, and individuals new to competitive mountain biking who do not require a federation license. Local parish associations and clubs assist in organizing the events, contributing to the series' distinct community-focused character over a large commercial event feel.
