Ahh Jura, one of the finest. Raced it twice, an the route 4 times total over the years.
I'd not bother doing a reccy of the "Pipps" before the Paps. Walk in from the bridge at the road, via the lake (t-Siob) and the hunters hides. Then walk/run the Paps.
Descent of Shiantaidh is fun. There is the line most will take, and a line that takes you down to the bowling green to get off - for this you effectively run at 145' from your approach to the control, then do a hard LH turn and drop down three scree runs, each going progressively rightwards until you pick up the trod. It's significantly faster. I can dig out map and find actual bearings if you really need them!
Descent of Corra Bheinn - just follow the ridge SE towards Alt na Corran then towards the bridge, it's pretty straightforward. If its been wet...have 'fun' its a bog.
As for the road...I've not bothered with road shoes. But I'm not bothering the front of the pack. However, I have dropped a bottle here the morning before when it was due to be HOT.
Frankly, if you are reccying, you want to find the spring after the first Papp - this is the most key part of the race if it's a hot day. Pretty much the only water until you cross a burn later on after Corra Bheinn.
If you've got the time - go visit Corryvrecken. You'll need a bike, unless you fancy a long run
Enjoy the race, it's excellent, as is the after party.
