@runliftrunlift @Alan_Couzens This is an interesting infographic! For athletes doing primarily aerobic training, how often per week do you typically prescribe strides? Is goal to build up to mile pace or go max from the start? The differential between easy aerobic and 1 mile pace is quite high so I’m curious

[Devon Main @Devinmain]

@Alan_Couzens I don’t expect to be in Kona qualifier shape after just 6 weeks of serious training. But I have been pleasantly surprised at how easily I’ve managed the added volume at low intensities. I got the idea from your great podcast with @feelthebyrn1. You can do more at low intensities

[Devon Main @Devinmain]

@Alan_Couzens Such a steep ramp means that my CTL currently corresponds to a sub -30 TSB, so I think fatigue might erode Kona qualifier readiness. I’ve always avoided such steep ramp rates for my athletes to avoid illness/injury but It seems low intensities allow steeper sustainable ramping?

[Devon Main @Devinmain]

@Alan_Couzens Years ago I was doing this kind of volume. But I haven’t for a long time. I’ve now maintained this low intensity volume for about 6 weeks and my CTL is nearing 120. TSB has been under -30 many times in the past 6 weeks. It stayed under -30 for 2nd and 3rd week. I feel great tho

[Devon Main @Devinmain]

@Alan_Couzens What are your thoughts on well-trained athletes pushing their TSB below -30 via aerobic volume alone? I have recently had the time to increase my volume substantially, I’m putting in ~20hrs a week @ < 125bpm (running and cycling). This is coming off only ~8hrs/week. LT1 ~ 135bpm

A new article argues that a new C. dilepis complex species is invalid under ICZN rules, the description does not uphold the claims made to define the new species, & that elevation of additional subspecies to species status are premature.

@Alan_Couzens @Sevhic_ I totally agree with this logic but surely with enough aerobic volume you will reach a point at which speed is your limiter on a 5K? i.e. if your 5k to marathon pace profile is pretty flat then doesn’t that suggest you need to do speed work to improve your 5K?

@drtristankapp Afrikaans was certainly influenced by Muslim and Khoisan culture but to claim that it is of Muslim origins ignores the fact that it is essentially a variant dialect of Dutch. Afrikaans is a Germanic language linguistically closer to Dutch and Flemish than Arabic.

@Brady_H I think the reason people struggle to comprehend this is that most people don’t actually put in enough volume when training for a marathon so their 5k time is their ‘trained’ time but their marathon time is very much ‘undertrained’.
