מומלץ לעבור על המדדים של ד"ר מיקלה פרארי, הוא פיתח מדד לבחינת מהירות הטיפוס. לינקים מצורפים: מה זה VAM? השוואה בין הרוכבים בנג"ש במון ונטו (דופין ליברה, מאי 2004). המלצה לכולם, האתר של ד"ר פרארי הוא אתר מרשים ומרתק, מומלץ לקרוא את המאמרים שלו. ולהציץ בפורום של האתר (ד"ר פרארי ואחיו סטפנו עונים שם על שאלות).

Superb time trialling Heras grabs his second victory in the Vuelta a España, thanks to a superb time trial performance, being able to climb the 600 m altitude difference in 22'28" (I subtracted from his final time the 2'40" it took him to ride the flat 2 km of the parcours). His VAM was 1600 m/h, a remarkable one considering the not-so-steep gradient of the climb. Nozal, a worthy adversary, collapsed probably more under the stressful responsibilities of the leadership than the fatigue over the three weeks of racing. Today in Italy there was the 86th edition of Giro dell' Emilia: a tough race with a tough final climb, the Colle di San Luca (220 m altitude difference over 2 km with an average gradient of 11%) which was to be climbed four times. The group with the best riders rode the first three ascents in: 6'08" (VAM of 2152 m/h), 6'12" (VAM of 2129 m/h), 6'15" (VAM of 2112 m/h). The last one was flown in 5'55" (VAM of 2230 m/h). Such a performance blows away Jan Ullrich's in 2001: 6'10" in a wonderful fight with Casagrande and Rebellin. It simply cannot be proposed to compare these VAM values with Vuelta's, but it subtly suggests the difference in intensity between one-day classic races and big stage races.

ההשפעה של מזג האויר הלוהט באותו יום בצרפת. Thirty-five degrees Celsius: this was the temperature at the beginning of the climb to Alpe d'Huez. It easily went up to 40° in some places for the riders, pedaling under the sun and on the French asphalt roads. With such high temperatures, the thermostatic temperature control of the body becomes a determining factor; a bigger volume of blood is sent right under the skin in order to lose heat with sweat, taking away oxygen from the muscles. The body's temperature tends to increase, sometimes reaching or even exceeding 39° C. If 39° C is exceeded, heat stroke might happen, with even more serious outcomes. Heavier riders have a smaller bodily surface if compared to their mass, thus it is harder for them to lose heat than lighter riders. Performances are indeed very affected by high temperatures: just think of how much slower athletes run marathons during summer months, in comparison with winter and spring events. In fact, en excellent Iban Mayo climbed the final ascent in 39:05 (VAM of 1735 m/h), two minutes slower than Marco Pantani's record. Farther back come Armstrong and the group of the best riders (VAM of 1640 m/h).They were all controlling each other, trying to avoid risks to keep something in reserve for the next few days, beginning with tomorrow's 9th stage, with Lautaret and Izoard, ending in Gap, one of the hottest places in France.

Adrenaline powered climbing Today Lance Armstrong attacked after only 13 minutes from the start of the ascent to Luz-Ardiden: Jan Ullrich dropped back a little, looked back and immediately decided to climb up his own pace, and a good pace indeed. A rather big adrenalin rush for Armstrong after another crash today ("It was my fault, I was pedaling too close to the public"). He immediately sped up to catch the main group, attacked and rapidly dropped everyone. Another 20 minutes of furious climbing awaits him till the top. Armstrong decreased his pace in the final kilometres, almost running out of sugars: he never took a single sip from his bottle during the whole climb. On the previous mountain, the Tourmalet, Ullrich set another fierce tempo with his typical full and powerful pushes on the pedals: a time of 44'30", with a VAM of 1700 m/h. Armstrong replied with a VAM of 1740 m/h towards Luz-Ardiden: a total time of 35'05". Impressive performances, for a total effort of more than 1h20'00: the big load of endurance workouts that Armstrong made this last year paid off today, even though the Texan rider is surely not at his best yet, after an endless series of more or less important inconveniences. זהו זה האחרון...
