Everesting checklist

I've put together a list of everything I can think of to get me across the line on this second attempt. have I missed anything?

I brought my MTB up last week and while the climb was easier, it was much to slow - although it may still be an option at the end when I'm completely shattered.

Think Light!

1. Bike clothing - bibs, jersey, socks, jumper
2. Heart rate monitor
3. Bike x 2
4. Helmet
5. Shoes
6. Sunglasses
7. Pump
8. Gels
9. Hydration (10 x drinks) + water
10. Food - sandwiches/banana's etc
11. 3 x battery packs – test these don’t reset the Garmin’s
12. 2 x Garmin bike computers

Marginal gains I've thought about which are worth thinking about as I ride.

1. Bike – keep everything off that’s not necessary. Take bare minimum tools if at all
2. Water bottles and food at car – drink and eat there and on the way back down
3. The start of the climb and the second pinch are the hardest – take these slow and easy – keep HR low – don’t start off hard and fast or you’ll run out of puff after the first few repeats
4. When possible (probably in the dark) keep to the high side of the road for easier pedaling as the road slopes downhill in the “S” bends (the inside line is much steeper and an energy waster)
5. At the top of the first pinch, take it slow and recover (road flattens). No need for speed. Get your HR down and breath back
6. The second pinch is tough. May have to stand near the top – take it slow and keep HR as low as possible
7. Up to the top of Flagstone – grind it out as easy as you can maintaining low HR. The “S” bends are steep – go steady and just push (seated). Don’t waste energy standing up
8. Rowbotham pinch – gets difficult half way up. Steady as she goes – may have to stand the final 30m or so
9. Exit roundabout and start the trip down
10. The Rowbotham/Flagstone intersection is dangerous. Stop completely and check the opposing mirror for oncoming cars from the right
11. The descent is rough, narrow and can be potentially dangerous. Take it slow and just cruise down – don’t be in a hurry to start the next repeat. Just get down the climb without face planting the bitumen! 
12. Wind will also be a factor. 
13. Be careful, look out and listen for cars both behind and oncoming. The road is narrow.

Anything I've missed here??
