They are fun, chilled out events, that don’t cost much and get you to ride trails you might not normally go for.
However,its not really a race, unless you can nav! MTBO has way harder nav than trailquest (which are genrally os maps), it don’t matter how quick you can ride if your going the wrong way……. I organised one a few years ago and took great pleasure in seeing a certain “Mr Fleeman, of road fame” get his ass handed to him by people of 50+ years who haddent gone over 20mph. It really puts folks on an even field…
