Yup - you need to tape up all the instruments - nothing is allowed on the bike that can give you any indication on how fast or how far you have gone.
So you have two options for the start of regularity - ride to the the start as quickly as you can, and then leave on time like you suggested, or ride the entire rally as best as you can on time, so that you are always within a few seconds of where you need to be. My Dad was a top rallyist when he was younger - I think he still holds the record for the lowest error in the DJ - thin
k it was 98secs over two days if I recall and he taught me a few things - one of them was to try and ride the entire rally on time and then ride the regularity sections exactly on time - the reason being is that sometimes the start of regularity is at an undefined point - like a farm gate or overhead wires. you get to a gate, start and then presto, there is another gate 500m down the road and you are stuffed for that section.
Kevin 81 409 -3 3 -77 -62 -53 -53 -15 60 -13 -9 19 18 8 -10 -6
Andy 82 306 -96 1 -25 -8 2 -15 13 -10 -2 24 18 63 -7 -1 21
Have a look above at my Dad's errors and mine - he was 3sec late at Marshall one, 3 sec early at Marshall 2 and then didn't practice what he taught me and raced to the the next start of regularity which just said "Farm Double Gate"- he started at the wrong one and carried the error over to the next 4 marshals - -77, -62, -53, -53
I knew I was badly out right from the start (-96) so I couldn't do that - I rode as best I could and actually got to the right gate only 25s late - then got back on time. -25, -8, 2, -15
So to answer - I prefer to ride the entire Rally as if I am riding regularity - it adds a bit more stress, but chances of cocking up are a lot less!
It depends on how good buddies you have! The top guys will not stop - but those riding at the back will just do it for fun - I would have definitely stopped to help my Dad.
Last thing - have a look at the top 5 times -
