[quote="skoptic"][quote="runner"]for a marathon training I would say min weekly around 70miles
As 50 mile is close to double marathon I would say you need more miles
Don't see any use in speedwork for ultra running
Sorry to say Runner, but as an ultra runner I disagree quite strongly with your statements. I think it's very personal how someone's body reacts to the mileage, how economic you are with your training and also what your goals are. I've run more ultras than marathons, but I've done both and never hit 70 miles in a week (I run a 3hr marathon and a 5:45 40 miler .. so I'm not plodding along)
I've spoken to a lot of ultra runners who promote quality speedwork and speed endurance work as very beneficial to ultra running, improving form and strength among other things. It's not all about more and more miles .. that can be a dangerous route to go down and one that I wouldn't subscribe to others.
Just my opinion.....
I don't say you can't run a marathon with <70mile, but this is the recomendation. What I wrote before there is also a max.
Individuals are different, but to a certain limit.
we are able to do many things, but this doesn't mean we should.
one question with regards to the mileadge could be if all people are capable to run marathons and ultra marathons in a decent way. Decent as healthwise. Problem is that other than in many other sports everybody can sign up for events without any fisical/ medical/ fitness tests.
suboptimal training leads to lower preformance and higher injury risk. both under and overtraining in combination with races are not something we should promote.
