show me where he said it would be "easy". He said he thought he could break the record and of course he would say that. If he said he couldn't, why attempt it??
I think he prepared as well as he could for this without actually attempting it before. Yes, his back didn't hold up but before that you have to admit he was doing great. I think from Calgary to Manitoba he was doing the ~110km a day and all was going smoothly until that herniated disc
The interview is here:
Actually Dave was not prepared as he could. He didn't have at least one successful 6 day race in his book. Just a "going out fast crash early" result from 1.5 years ago.
I still have to look at the numbers from the last 3 weeks but Dave did not do great in the beginning. Started out very fast with too many miles. His main flaw was that he ran too fast. You have to run multiday races with the least amount of stress to your body. If he would have done the same mileage with 2 more hours it probably would have been better.
Pete Kostelnick had a successful run through Iowa I think a couple years back. After too many miles in the first days, he adjusted nicely with (what I thought was a weird ass move) a day of no running. It worked. After that he ran 72-74 miles every day.
At the end you can't copy other peoples running since you only have your own body to work with. The art is to make the most out of your body without breaking it. That is the most important skill set for a multiday runner. 24 hour results are meaningless for that. Some of the most successful 6 day runners where not very good in 24 hour races.
As always, this is very difficult to explain to non multiday runners. Even most 100 mile and 24 hour runners overestimate what they can do on a day to day basis.
