I had not expected that my theoretical play with these figures was taken so seriously ;-). Some of those personal bests were from relatively long ago &#8211; for example, the 261.475 km by Ron Teunisse dates from Apeldoorn 1990 (and is still the National Best over 24 hours for the Netherlands) and the 276.209 km by Wolfgang Schwerk dates from K\u00f6ln 1987 (and is still the National Best over 24 hours for Germany).<br \/>\nBut I rather doubted whether these very good runners from the recent past were still able to repeat such performances. Nevertheless, even I had some confidence in the validity of the figures as an index of relative strength of the participating teams. In fact, that very day October 10 that I published these cumulative results, I also made my own predictions for the top five teams in Uden. Unfortunately, I did not list my predictions as I thought that such nonsense would be regarded as idle pomposity ;-). Looking back, my predictions were no too bad, so I dare now to insert these in between the real and the theoretical results.<\/p>\n<p>{fixed}<br \/>\nWomen teams World Challenge 24 hours<br \/>\nFinal result top seven   Martien&#8217;s prediction  Theoretical top five (cumulative PR)<br \/>\n1  Russia  684.858       1 Russia  660.000      1 Russia  696.485<br \/>\n2  France  649.303       2 France                2 France  667.367<br \/>\n3  Japan   628.440       3 Germany              3 Japan   638.771<br \/>\n4  USA     597.038       4 Japan                4 Hungary 628.205<br \/>\n5  Germany 594.304       5 Italy                5 Germany 608.299<br \/>\n6  Hungary 591.237<br \/>\n7  Italy   565.751<br \/>\n{efixed}<\/p>\n<p>The final ranking of the top five women teams was nearly conform their cumulative PR ranking,<br \/>\nexcept that the USA instead of Hungary reached the 4th position. In my personal prediction,<br \/>\nI ranked 4 of the 5 final top teams in my list. It is clear that I failed to insert the USA,<br \/>\nbut credited Italy two places too high compared to the final result. Note that my prediction<br \/>\nof the winning team distance was a bit too low, the three Russian ladies came to a new record<br \/>\nhigh of 685 km! Irina Reutovich (1) and Irina Koval (7) were not so far from their PB&#8217;s, but<br \/>\nGalina Jerjomina (2), the surprising runner-up, smashed her own PB with more than 25 km.<\/p>\n<p>{fixed}<br \/>\nMen teams World Challenge 24 hours<br \/>\nFinal result top seven   Martien&#8217;s prediction    Theoretical top five (cumulative PR)<br \/>\n1  Belgium 791.901       1 France  740.000      1 Germany 792.917<br \/>\n2  Russia  739.569       2 Russia               2 Belgium 784.700<br \/>\n3  Japan   729.956       3 Japan                3 France  781.650<br \/>\n4  France  715.792       4 Belgium              4 Russia  771.370<br \/>\n5  Italy   713.362       5 USA                  5 Japan   756.401<br \/>\n6  USA     688.413<br \/>\n7  Germany 685.205<br \/>\n{efixed}<\/p>\n<p>The final ranking of the top men teams was a big surprise as Belgium was the very proud winner<br \/>\nand Germany only came 7th. The team result of nearly 792 km by the Belgians was record high &#8211;<br \/>\nas Ton Smeets already remarked in an earlier message &#8211; and both Paul Beckers and 51-year old<br \/>\nrookie Etienne van Acker improved their PB&#8217;s. The 270.087 by Paul is a new Belgian record, the<br \/>\nold one was 267.500 by Lucien Taelman. I guess that not many people in the world would have<br \/>\nexpected such a dream team result of 792 km, at least my own prediction of the winning team result<br \/>\nwas 50 km lower! It is clear that beforehand I was not convinced by the high theoretical cumulative<br \/>\nPR by Germany, so they were not in my own top five prediction. But instead of France, I ranked<br \/>\nBelgium just outside the podium, and I hope they will forgive my underestimate.<\/p>\n<p>So what lesson can be learnt from this exercise? There is a lot of truth in the cumulative PR but one has to take into account the dates of the PR&#8217;s and the current form of the runners. Last but not least: team spirit must be high as well. Look at Lucien Taelman of the Belgium team: after about 18 hours he was relatively broke down and it became clear that he was out for the podium and even had no chance for improving his own PR. But he just hung on and made the final result an unprecedented 1-3-5 for Belgium!<\/p>\n<p>Martien Baars<\/p>\n<p>PS To make my own position and intentions clear: the above, and all other activities, are not to be ment as open &#8216;applications&#8217; for formal jobs as team manager or as delegate in whatever international body.
