Its only a short 3.5 mile race.
Its totally on my doorstep and I train on the hill regularly and have done for over 15 years.
I know it like the back of my hand.
The weather was, well, interesting! 17 degrees in December?
But there had been slinging rain and dense mist shrouded the summit and the mid slopes to varying extent.
I was racing well. The ascent was hard but I felt great. The course was well marked. Hitting the descent, I took my time because it was treacherously slippy. I couldn't see any markers but viz was very low and, anyway, I knew where I was going. I had half a dozen followers coz they knew I was a local.
Except somehow I went 90 degrees too far east and ended up adding half a mile to the route by the time I corrected my error.
A comfortable midfield position slipped to a last quarter position.
In the circumstances the most I paid was embarrassment and loss of league points.
Had the temperature been zero (quite possible) the consequences could have been much worse.
Lessons: To me - always take a quick bearing in poor viz.
To the others - never follow someone. Take responsibility for your own route in poor viz!
The Skirrid Race - Fantastic!
