UltraBirken-2010: Preparations

Gjerdingen, Nordmarka

First upcoming event is an ultrarace on trail-UltraBirken. It's due next Saturday.
Distance is 73 km and most of it is on trail. Start from Rena(7 a.m.) and finish in Lillehammer.
My target with this race is to finish faster than 10h. In order to do that I need to have an average pace of 8 min/km. That's within my reach.
The course is divided in the following parts:

1. Rena-Skramstadsætra(D)         : 15 km, on gravel roads
2. Skramstadsætra-Åkersætra(D) : 17,5 km(32,5 km from start), trail and mountain running
3. Åkersætra-Sjusjøen(D)            : 17,5 km(50 km from start), very technical trail on marshland
4. Sjusjøen-Finnsveen                  : 14 km   (64 km from start), gravel roads and light trail
5. Finnsveen-Lillehammer             : 9 km     (73 km from start), gravel roads and light trail
D: Drop-point

Theoretical I have the opportunity to supply myself at three aid-stations(2, 3 and 4)
The first part of the race is easy to decide on when it comes to shoes. I'll use some light-weight shoes.
From point 4 to the finish line I'll use trail-shoes. That goes for the part between part 2 and 4 as well.
I'm bringing three pair of shoes.
1) Mizuno Wave Ronin for use from the start till Skramstadsætra(15 km).
2) Puma Trailfox for use between Skramstadsætra and Sjusjøen(35 km)
3) Montrail Masochist for use between Sjusjøen and the finish line.(23 km)

-Goal, overall: finish on 9h 45m (average pace of 8,0 min/km / 7,5 km/h)
