A few friends have expressed interest in doing the Snowdrop next year, so I thought I would throw out my thoughts on what I did right and what I could have done better.
First and foremost, whatever else happens, make sure you get your long training runs in. My training for about a month before the race went sideways, and I paid for it in additional pain. Long runs are time-consuming and tough to fit in the schedule. Find a way.
Get your foot care regimen sorted out well before showing up. The more you prevent, the less you have to fix. The foot medic they have there is awesome, and you should not be shy about going to see her, but the better you do at preventing problems the less you will need patched up.
The tent sites are inside the loop that you will be running. Make certain that where you pitch your tent is at a local high point, as the lower areas flood when it rains. (A few people brought pallets to make a walkway across the low spots and help keep feet dry.) The site can be windy, so when you come to set it up bring enough gear to weight it down. Also be familiar with your tent, as mine would leak if I didn’t position gear to push out the walls. Having a dry place to catch a 20-minute rest can mean the difference between moving on with high spirits and standing there wondering why you thought you could do this.
In addition, a rain shelter outside of the tent (with chair and waterproof gear bin)would have been great. It would have been much easier to be able to tend my feet and grab pain meds without having to crawl into the tent. There was a significant amount of time I refused to stop for gear, worrying that I would stay in the tent and not want to move. Having gear dry outside would have made it easier to grab what I needed without stopping.
Having some piece of gear that you can put your feet up on when you lie down helps enormously. I used the rucksack that had all my extra clothes.
The food selection is awesome. Eat a lot. Drink a lot. Do not allow yourself to feel hungry or thirsty. You know that calories and water in are going to be an issue, so head it off before it becomes a problem.
Bring all the socks you own with you. Bring several pairs of broken-in shoes. If you have different styles for different trail conditions, bring them and change as conditions change. Bring extra clothing in more than one style (i.e. if you usually wear compression, bring some loose-fitting stuff). The compression shorts that served me well at 50 miles were killing me by 75, and my jersey seemed to be strangling me by mile 60. If all I had brought was multiple sets of the same clothes, I would have been in trouble. Changing into boxer-briefs and a loose T shirt fixed the problem. Also, bring rain gear. You may be able to take a break when it rains, you may need to keep moving through it.
Plan for as many things to go wrong as you can think of. You are less limited in the gear you can bring here than in any race I have ever done, so take advantage of that fact.
