Fair enough if u already done two oceans!! I did have MdS on my wish list but I think it's a bit overpriced and now there are plenty of other multi day stage races Around. a friend who has his own ultra running events set up makes a fair point that something like 99% of people who start mds also finish it. SM75 I did the other day had about 50% (maybe a bit less) finish. I have my eye on the equivalent race in Namib dessert or I've just seen a company pop up in Australia- they are advertising an equivalent race in the Simpson dessert but it looks like they may also be planning one that incorporates Uluru. I rrally wanted to go there but when I liced in Oz just didn't have the funds to make that trip in the way I would have wanted.
Comrades was in my wishlist until my ex-boss who used to work in S Africa suggested that the 2 oceans would make for a much nicer holiday- Cape Town, vinyards etc..., those videos of comrades when the cutoff strikes and people are literally a few metres away rare gut wrenching.... Why not do both? Comrades is spring isn't it- you could then work up to IM late summer, knowing the running is well and truly under ur belt
