I was watching Sky Sports Racing yesterday - conditions looked absolutely foul!
Ground was "good", changing to good to soft after race 2 according to Racing Post. That seemed hopeful, looking at all the non-runners and horses strewn out like washing by the finish of many of the races. I wonder how mnay horses down tools in heavy wind though - I know I can;t stand it!
Wind & Racehorses -
It's not about horses "downing tools"

matty1976 - racehorses don't have that mental frailty that humans do, they have as a breed been carefully selected and trained to do one thing over hundreds of years - race. If racehorses are internally sound and feel no pain they will run to the level of exhaustion and be in the "red zone" of endurance far longer than any human.
So how does wind affect performance then ?
We know that wind has an effect on racetimes - therefore the pace of the race. Given that horses run within a tight tolerance of distance range due to stamina limitations then wind can have a massive effect. A pack of racehorses running into a gusting 20mph headwind are slowed on average by as much as 8-10 lbs per 60 seconds. The effects of running WITH a gusting 20mph tailwind behind are speeded up slightly less than that per 60 seconds. More damaging though can be the cross wind where at gusts of 20mph within a constant windspeed of say 15mph that can have a "sail" like effect on the pack, especially those more exposed and without "cross-cover". Horses have un-proportionally large "sides" plonked on top of very spindly legs in comparison, so when the cross wind hits those sides (near side/off side depending on direction) become like large "sails" which retards speed and causes more resistance to the mechanics of running - the horse will still run - only slower.
Where a horse is placed in the pack is also important when looking at wind as some will "draft" through cover and be less affected and some will be more exposed, so when the race really starts and maximum effort is called for, some will have more energy left than others. Smaller fields will be less prone to effects than larger fields whilst a pack of professional experienced jockeys will be less affected than inexperienced conditional jockeys. Also the speeding up/slowing down effect is not exactly linear - I used 20mph gusts/15mph constant above as an example but the effects become much larger with even small increases of wind speed/gust speed over that. So race times can be stretched or condensed by windspeed - the going may have been in the degree of "good-soft" yesterday but the times (which are in effect "distance") looked stretched to correlate to "heavy"
One other area though where winds of the magnitude of yesterday will have is through "sound" - horses are highly sensitive to noise - winds of that magnitude yesterday produce a tremendous sound and this can affect concentration and focus by distraction and also cause an increase in heart rate.
Lastly and again winds (on the scale of yesterday) can affect the respiratory system with those prone to breathing or "wind" issues (no pun intended) in the past being more affected.
As a breed though they still run in all sorts of conditions and successfully too - again, if no pain racehorses will run and give their all until they are exhausted. Before they even get to that point they have a far higher level of "running on empty" than humans.
Should a punter be wary of "form" of races run in the extreme wind conditions experienced yesterday at Hexham??
Oh fuck YES. With the attrition rate looking to increase as the meeting went on and a total of 22 of the 56 runners being eventually pulled up (~40%) I'd venture to say that it is highly probable that the majority of those races are worth very little and not a true reflection of ability.
Looking at the results yesterday and any lessons to be learned going forward - in the vary last, a handicap chase over 3m where wind and gust speed were at their highest, there were 4 horses in a field of 9 all with tongue ties on (suggesting previous breathing/respiratory issues) - that those 4 all were at the front of the betting could have been a "way-in" to the race - they filled 4 of the last 5 places. Also notice that there was a horse returning from "wind surgery" (again no pun intended - wind issues usually involve the process of air inhalation) last time in the race before that and was backed down to favouritism - he finished over 60 lengths behind the winner.
Maybe some contextual things to look for the next time we know that races are going to be run in extreme winds.
