Course Details?

For the 28th Sultan MDS, there has been some changes to the general event format as compared to previous years. While the uncertainty of the event/course is part of the fun, I still like to know somewhat what to expect.  This is what I have gleaned from postings on the MDS website:

From "The starting line is in the sight" (love how things get distorted in translation)

• Five competitive stages totaling 230km (143 miles)
• A"difficult" course
• Untimed liaison stage of 7+km (4+ miles) at the end

From "The Week End 28th Sultan MDS" and the Terres D'Aventure brochure:

• Liaison stage to be conducted on the 13th
• Marathon?/final stage of MDS on the 12th

So what does that mean, or how I interpret this information.

• One marathon length stage (26+ miles)
• Assume one 50 mile stage
• Leaving about 67 miles for the remaining stages or an average of 22+ miles each (I am expecting these will vary significantly in length)

Estimated schedule

5th: Bivouac
6th: In-processing
7th: Stage 1
8th: Stage 2
9th: Stage 3
10th: Stage 4
11th: Stage 4
12th: Stage 5 (Marathon)
13th: Liason/Back to Ouarzazate
14th: Ouarzazate

Only time will tell!
