Tour of California vs. Tour de France
In the world of cycling the biggest race of them all is the Tour de France. The prestige, popularity and history of the race make it the penultimate cycling event for cycling fans and professional racers alike. The race has stood the test of time and is quite possibly the hardest sporting event in the world considering it lasts three weeks, forces the riders to race for up to seven hours a day, and covers some of the highest roads in Europe.
The Amgen Tour of California can’t compare in terms of legendary status, and with only eight days of racing the California tour is roughly only one-third the length of the Tour de France. However, the recent 2010 edition had many riders and team staff members saying it was too hard. In fact if you look at the results for just the sixth stage between Palmdale and Big Bear Lake (7,000ft above sea level) eleven riders didn’t make it to the finish line within the 9% cutoff time, and 17 starters simply decided to drop out. That makes 28 riders who never made it to the start of the stage 7 time trial in Los Angeles. Less than half (63) of the 128 starters actually officially finished the entire Tour of California.
Perspective from a Grand Tour Veteran
Team Saxo Bank’s Rider Development Manager, Bobby Julich, had plenty to say about the most recent edition of the Tour of California when asked how hard the Big Bear stage was. “The Big Bear stage was one of the hardest stages I have seen anywhere. It was solid climbing right from the start and then never let up. I think that the hardest part of the stage was that it was almost all at altitude and was over 220km long. That was truly a grand tour like stage, and perhaps even harder than most. I was a bit surprised to see a big group finish together at the end, but just goes to show that many riders were on form and motivated for the Tour of California this year.”
Ok so the Big Bear day was hard, but how hard was the Tour of California to finish? Was America’s most prestigious event simply too hard and if it continues to be as demanding will it be to the detriment of the event moving forward?
Julich provided his unique insight to this debate, “When you look at the way the race came down to the time trial, you would imagine that it was exactly the same type of race as years past, but I can tell you that the guys were already exhausted after the 3rd stage into Santa Cruz. The organizers elected to put some sort of climb into almost every stage, so there was never time to relax and recover in the race. With the date change, many US based teams were motivated and they wound up cancelling each other out on many of the difficult stages. Everyone did their homework and prepared well, but I was surprised to see such small time gaps at the end. I hope that this doesn’t make the organizers try to find an even harder route for next year or else it could scare away some of the European guys that were using this race to get started again after the classic season. Perhaps the organizers should think about making the final of the stages a bit more selective instead of having the real “teeth” of the race often far from the finish.”
Comparing The Tour of California to the Tour de France
It is hard to argue with an experienced rider such as Julich who himself has finished on the podium in the Tour de France. In an attempt to add some objective data to Julich’s opinion we might find some answers by simply comparing and contrasting the eight hardest consecutive stages of the 2009 Tour de France with power files collected from this year’s Amgen Tour of California.
In terms of reviewing Tour de France race data we chose to use power files collected during stages 2-9 of the 2009 Tour from Team Saxo Bank’s Chris Anker Sorenson’s. Sorenson’s race files can be seen here:
As for 2010 Tour of California data we looked at power files from Darren Lille of team Fly V Australia and Jakob Fuglsang of Team Saxo Bank which can be found here:
To help determine how hard the Tour of California was we narrowed down the race data to look at five different categories:
The Hardest Stage as Measured by Most Kilojoules
The Total Kilojoules Measured for the Eight Consecutive Days
Duration (Hours) of Accumulated Winning Stage Times
Hardest Stage Measured by Training Stress Score® (TSS®) Value
Total Accumulated (Eight-Day) TSS Points
Kilojoules- The Hardest Stage
Lill- 4844kj, Stage 6: Big Bear
Fuglsang- 6364kj, Stage 6: Big Bear
Sorenseon- 5652kj, Stage 7: Barcelona to Andorre Arcalis
This is a toss up. There is no clear winner here. The hardest stage in the Tour of California for both Lill and Fuglsang was stage 6 with 4844kj and 6364kj respectively. Sorenson recorded 5652kj within stage 7 (Barcelona to Andorre Arcalis) of the Tour de France. The reason why Fuglsang’s kilojoules were so high is because he was in the breakaway for nearly all of the stage so his intensity was much higher than Darren Lill’s who rode within the main peleton. Eventhough there is no clear winner within this category the Big Bear stage in California absolutely measures up to the hardest stage of any Grand Tour
Total Accumulated KJ’s
Lill- 28,221kj (avg 3,527kj/day)
*Fuglsang – 29,061kj (avg of 3,632kj/day)
Sorenson- 31,479kj (3,934kj/day)
And the winner is the Tour de France at an 8-day total accumulated value of 31,479kj and an average of nearly 4,000kj a day. The Tour of California is just behind with a daily average of just over 3,500kj a day.
*Fuglsang- Stage 8 is not available so we can assume it was around 3,000 based on Darren Lill’s power file and the two finished in the same group together tied for 40th place 15’ down.
Winner’s Accumulated Stage Times
The 2010 Amgen Tour of California’s winner, Michael Rogers, completed the race in 33hrs and 8 minutes, as compared to 33hrs and 3 minutes for the accumulated finish times for stages 2-9 for the 2009 Tour de France winner Alberto Contador.
There is no clear winner within this category. The times are almost exactly the same.
Hardest Stage Measured by Training Stress Score (TSS) Value
Lill- 361TSS, Stage 6: Big Bear Lake
Fuglsang- 431TSS, Stage 6: Big Bear Lake
Sorensen- 391TSS, Stage 7: Barcelone - Andorre Arcalis
TSS® is a very valuable metric to track since it takes into account the intensity of the race as compared to the individuals own functional threshold power value. Besides an Intensity Factor® being accounted for, the TSS value also takes into account the duration of the race. This has much more meaning than kilojoules since kilojoules do not account for the relative intensity of a race. What might be a threshold pace for one rider may be a lower tempo type zone for another, yet if the two riders weigh the same, and recorded exactly the same watts, the KJ’s would also be the same.
Yet again another toss-up here. Fuglsang recorded an enormous 431TSS points since he was in the long breakaway group. In contrast Sorensen measured 391TSS points within stage 7 of the ’09 Tour de France. Fuglsang would have had a lower value if he hadn’t been off the front for so long. It seems as if the hardest days in the grand tours measure around 400TSS points.
Total Accumulated (Eight-Day) TSS Points
Lill- 2254 TSS total
Fuglsang- 2192 TSS
Chris Anker Sorenson- 2152 TSS
The Tour of California had a slight advantage when you compare the total accumulated TSS values of the two riders in the Tour of California versus Sorenson’s highest eight-day accumulated value from the Tour de France.
Now of course it goes without saying that the Tour de France as a whole is harder since it is three weeks long, but now we can see how the Tour of California is just as difficult as the hardest week of the Tour de France. The US domestic teams certainly deserve a lot of credit for any amount of success they find at the Amgen Tour of California. The race has evolved to a level where the European-based riders can’t simply show up with sub-par fitness. Just finishing the Tour of California now pushes each rider to the limit and keeps pretenders away.
Whether this is good or not for the future of the Amgen Tour of California is yet to be seen. One thing that is certain is if the race continues to be as hard as this year’s edition some of the bigger names in the sport may opt to skip the Tour of California as their classic’s season ends.
