How to improve my running speed over a long distance.?
I would also recommend strengthening your core. BUT instead of going for bulk, I would try for lean muscles. For example, instead of doing 3 sets of 3-5 repetitions of a heavier weight for yourself, do 3 sets of 10 repetitions of a weight that would get you tired on the last 3 repetitions of each set. I would also include doing anywhere between 3 and 13.1 miles for each run, doing strides/sprints at the end, and making sure you stretch. Make sure you have a long run, but NEVER do a long rung amounting to your final run (26.2 miles). Make sure you eat well too. Feel free to contact me if you have any more questions.
