410. Don’t Train in Vain: Speed-work for a Multi Day Race?

For More Endurance Noise & Random Musings! Show Notes: Listener Question I've been very unsure about the role of "speed work" in my training or if there is any role for it when my slow training pace is already a touch above my targeted maximal race pace.  Perhaps you have some opinions and wisdom on this topic. First rule is to stay healthy and get to the start healthy. Boring makes you strong and speed kills. 400 miles in 6 days 66.6 / day. 18 pace is 20 hours Closer you get to race the more you should do race paced work. Further out you can do shorter / faster work. Speed is mainly for form purposes and to add some variety to your routine. Do some short races like 5ks and 10ks just to get out of your comfort zone sometimes. Speed kills your feet. So be sane on day one. Set a reasonable mileage goal / time goal for each day and have your breaks planned. Holder, Winkley and Fejes do this.
