I had teammates in the NCAA run 28:40 off of similar workouts like 10xk in roughly 2:45 with a 90" rest. This was at sea level and on an indoor track so probably a difference of ~5 seconds a rep, maybe less with shorter rest. The best indicator for what you can do a half in is whatever pace you run for an 8-10 mile continuous Tempo at sea level. 10xk with a 2 minute rest is just vastly different than a half. How many times have you seen your conference rival rip a bunch of fast k's just to get smacked in Cross or on the track? Without lactate measurements and heart rate data it's hard to tell how hard someone really is going in a workout or what it could correlate to. He also labeled this as a VO2max effort workout in his Strava which doesn't seem right to me. Science says VO2max effort can be held for 8-10 minutes max while running so I doubt he was getting in 25+ minutes of work in at that pace.
He's way fitter than I'll ever be but I doubt this workout really indicates anything more accurately than a Tempo workout or hill repeats would. Hopefully he gets to the line healthy and gives the 1 hour barrier a scare.
Okay well it’s not smart to do every many indicator workouts now is it? So him doing this workout at this time is actually very smart of him
As I said. 10xk was not a good indicator workout. The demands are not similar at all to a half marathon. He was clearly in good shape but nothing in training suggested that he was "absolutely" in AR shape.
The point was that a 28 high guy could muscle through a similar workout and that we don't have the lactate/heart rate data to make any determination on how easy/hard the workout is for him physiologically. It's not a good race indicator workout beyond just the general knowledge that you're in very good shape. Who knows if 10xk in 2:44 at altitude equals out to 62 minutes or 59 minutes? Hopefully it means 59 minutes but the best person to ask when it comes to this would probably be someone like Canova who's coached a dozen 59 minute guys.
So you’re saying Klecker is in 28 high shape? My god I don’t think that at all
Circling back to this after I've been vindicated again. Most of what Ritz has had Klecker doing in training is just not very Half Marathon specific and people need to stop pretending like decent 10k workouts predict 59 minute half fitness. If you want to know what Klecker is capable of for a half then tell Ritz to have him spend 2-3 months building Tempo volume up to 8+ miles consistently in workouts and then see whatever pace he's running in an 8 mile Tempo. Klecker has what it takes to be a fantastic half marathoner I'm sure, but the preparation hasn't been in line with what many great half runners have been doing for years now.
