You can't beat the mountain bike for getting you out in the midst of nature, surrounded by the flora and fauna.
However, this group of Irish mountain bikers saw a whole lot more than that when out riding. Instead of spotting the usual kind of birds and bees, they came across a couple coupling rather vigorously at the side of the trail.
After riding past the pair, the rider with the helmet camera almost did himself a mischief laughing at what he'd just seen.
We assume the mountain bikers continued with their ride afterwards, but we've no news on how the rest of the couple's afternoon faired after being caught in flagrante delicto.
Ever seen something similarly unexpected out on the trail? Do let us know in the comments.
