Just back from the Fair City Enduro - good day out and enjoyed myself. 4 MTB stages (1 sharp climb, 2 muddy rooty singletrack blasts and a bike-park-jumpy-type thing like the bottom of the blue at GT, plus a final stage with some trials-lite obstacles on the park beside the car park.
Good things: Atmosphere, not very racey at all, ended up going round the loop with the same folk and chatted quite a bit on transitions. Good course, some tricky bits and some flat out pedally sections - was really good to be able to ride natural/shared trails fast without worrying about someone coming the other way round the corner. Think the format would lend itself well to a bunch of mates entering.
Less good things: A LOT of waiting before the first stage (well over an hour as I was near the back. Think this could be sorted by staggering the start in waves though. Overall less riding than you'd usually do in a day and felt like a lot of climbs per smiles, but still a nice way to experience new trails. Not sure I'd do one somewhere I knew like GT. Mud + roots = crash (only one though, and all it cost was a bust shifter).
If you get the chance I'd have a go at this enduro thing, pretty chilled for a race and it's the kind of riding we all do anyway.
Did I mention it was muddy?
