Faster, Older, Younger?
It has been a while since I did a post with a hardcore “human limits” angle, but some impressive middle and long distance running results over the last couple of weeks make the time ripe for a few observations. So, here goes!
Is 45 the new 35?
In mid-February the 40 year old and seemingly ageless Bernard Lagat went 3:54.91 for the mile at the Millrose game in New York City. The previous best time for a 40+ was 3:58.15 by Eamonn Coghlan – the “Chairman of the Boards” set in 1994. Lagat went 3:51:38 at age 36 and his best mile time is 3:47:28 at age 26. Who knows just how fast he could go if he focused on the mile and ran five or ten highly competitive races in the next several years. My bet is that he could run at least a couple of seconds faster.
I also bet that if Lagat continues to train for the next five years, he might be able break 4 minutes in his middle 40s. If top competitors can avoid injury and keep training hard, it is possible for them to maintain their fitness at a level near the peak values typically seen in their 20s. However, even the most dedicated and injury free trainers start to lose something in their 40s. The minimal rate of loss for maximum oxygen uptake is probably about 4% from age 40 to 50, and this is a key determinant of mile time.
So if Lagat lost only 2% in the next 5 years that would slow his mile time by about 5 seconds and his projected age group record at 45 would be 3:58 to 3:59. The old timers reading this will remember that in the early 1970s four-time Olympian George Young broke 4 minutes in his middle 30s. At the time that seemed both inconceivable and unbelievable.
I wonder if and when we will see a sub 4 minute mile by a 50 year old?
The world record for the women’s marathon is 2:15:25, set by Paula Radcliffe who also owns the two next fastest times and no one else has broken 2:18. Her marks are true outliers and a number of people wonder if and when the field will “catch up”. On February 16, Florence Kiplagat ran the half-marathon in 1:05:09 which converts to an estimated marathon time of just less than 2:16. A few days later Genzebe Dibaba went 14:18:86 for 5,000m. That time is equal to about a 2:17 marathon.
The chart below is from an analysis that Sandra Hunter, Andy Jones, and I did on the 2-hour marathon “equivalent” for women. It shows the 100 top men and women’s times as a % of the world record with and without Radcliffe’s times. Based on these recent times at shorter distances, perhaps the men’s and women’s curves might start to look similar as more women run times between 2:15 and 2:18 in the next few years.
That having been said, it will be interesting to see if Paula Radcliffe holds the three fastest marathon times for women in five years. My bet is no.
Last week Tim Kruse who worked in my lab prior to starting med-school at the University of Washington sent me an e-mail pointing out that about 20 collegiate male runners broke 4 minutes for the mile in February. In response I asked where these guys came from and he drilled down on it a bit and said that 13 came from the U.S. and several more from Canada.
The question then became why? Better training? A bigger talent pool? Better tracks? Doping? I bounced these ideas off David Epstein, Alex Hutchinson, Amby Burfoot and Rickey Carter. The general consensus was that doping was not a major issue. Better tracks and better competitive opportunities likely played a role. However, several people commented on the role internet and dedicated track and distance running sites. These sites (like LetsRun) promote the sport in general and are also a great forum to share information about training and also inspirational stories. My guess is that they have been catalytic.
Amby pointed to an article he wrote a few years ago about the “turning point” in U.S. distance running being marked by the 2000 Foot Locker High-School Cross-Country Championships which featured Alan Webb, Dathan Ritzenhein and Ryan Hall. Evidently these guys had been more or less stalking each other for some time via an early internet site devoted to high school running. Amby’s article is a great read and really nails the reasons behind improved middle and long distance running in the U.S. in specific and N. America in general.
That having been said, the depth at the collegiate level indicates the North American talent pipeline for middle and perhaps long distance running is as full as it has been in many years. It will be interesting to see if this ultimately translates into things like more international top 10 rankings, victories at major competitions and even Olympic medals.
My bet is that the East Africans might not seem so invincible in 10 years.
A Good Month
It was a good month for middle and long distance running that makes me as optimistic about the future of “my” sport as I have been for a long time. The growth of mass participation distance running by people committed to fitness has been the big story over the last 10 or 20 years. The re-emergence of a sizable number of elites in North America has the potential to be the frosting on this wonderful cake.
