I've been thinking a lot about what has been said about the success of Kenyans(who arguably have been the most successful at the marathon) etc...on these boards.
It seems that the general consensus is that they have a range of both genetic and cultural features that allow them to do so well on the world stage.
ie
-born at altitude
-having ideal runners bodies (long legs, short torso, large lungs, low BMI)
-in many cases having had an early development of aerobic capacity via running to school in bare-feet etc... which has also honed their footstrike and efficiency.
How would you now make up for a European-American runner who has missed out on these cultural advantages which the Kenyans have not? A lot of young Kenyans start racing really fast times heading into their early 20's. This might be because they already have a massive aerobic base under their belt, which they got at an early age. This enables them to quickly fit into a American/European system and excel.
My reasoning is that it should be possible for a runner who has not started off as young as the Kenyans have, to still achieve the same aerobic development heading into his mid 20's.
Aren't American runners (pro as well as collegiate) doing this??
The way I see it; most top end American runners are doing a cycle of base phase, hills/vo2max whatever, anaerobic phase, peaking- race season etc. The good ones are putting in plenty of aerobic miles, 100+ a week during base phase. They typically start this cycle maybe in HS, then college. If they are good enough to turn pro (obviously have talent), continue running etc.... the chances are they will continue along these same lines of training regardless of coach. They race 1500 to 10000 during the ages of 18 to around 30. Then they switch to a different style of training when they turn to the marathon (Culpepper?? something along these lines) Their new approach is a lot more aerobic, usually only targeting one race per season and without the anaerobic portion.
They do okay.
At no point in their careers leading up to the switch to marathon have they focused on sustained aerobic mileage for more than 10-25 weeks during base phase right?
By that time it's to late, bye bye...
The Kenyans have already put in (on average) at least 4-5 years straight training during their childhood/early teens. They've already done it.
I always hear people say, don't bother with the marathon until later, get some speed first.
Why????
Wouldn't it be more advantageous to focus on the marathon from 18-24, then if you want return to the shorter distances do so then?? Even better start with the marathon straight out of high school and aim to peak around your early 30's.
Sorry if thats a bit of a ramble, but any discussion (+ or -)would be appreciated.
