I recently started listening to your show and am really loving it. I’m a physical therapist by “trade” but have also run multiple marathons and identify more as a runner than a PT. I’ve had a few kids (which cuts into training!) and am starting to get back to it. I have a few questions and just curious what your thoughts are. I’m both a coach and a competitor so I’ve got questions for both sides.
1. What are your thoughts on multiple MAF runs in one day? I’m training for my first 50 miler and, because of my work/life schedule, multiple runs in one day is how I get a lot of my miles in. Is there a minimum time needed to get benefit? 30 minutes? Obviously, “how little to train” is just as murky as “how much to train” but I’m curious if there’s any data you suggest as a minimum needed to cause physiological change.
2. Is there any significance to the drop off that occurs in a MAF test? Example: a 4 mile test with a total drop of 15 sec/mile (9:00 min/mile @ mile 1 to 9:15 min/mile @ mile 4) vs. a 45 second drop off (9:00-9:45). Would an earlier/quicker drop off be related to lack of condition vs. later/slower be a nutrition/energy availability issue (just a thought)? Is there a difference in how you would train these athletes? (Not sure what average drop off would be so I apologize if I’m way off.)
3. In thinking about question 2… what about drop off during training? How far do you let your pace drop? And can you use the “rate” of decline to plan nutrition intake during marathon/ultras? Or is it only useful to monitor progress in general terms?
