The long run is obviously the most important training session of the week for an ultra runner but how long should it be?
I was initially of the opinion that longer was better but after building up to a long run of 75km before my first ultra and dying big time in the race I re-evaluated my ideas.
For my second race my longest run was only 45k and it was run at a much slower pace than my previous long runs. This was a resounding success as I was still running strong with 95 miles of running in my legs.
Why the big difference and why did running less ks at a slower speed in long training runs result in me running more ks at a faster speed during the race?
