  • Power Analysis: Amgen Tour of California, stages 1-2
    Chris Butler averaged 254 watts on the 10.7-mile ascent of Mt. Palomar in stage 1 at the Amgen Tour of California. Photo: TrainingPeaks

    The Amgen Tour of California started with two scorching hot and hilly stages. The true challenges of these stages proved not to be the terrain but the heat — dehydration of as little as 2 percent of body weight (about three pounds for a 150-pound person) can affect physical performance and raise heart rates by about five beats per minute. Dried and crusty salt stains were visible on everyone, indicating the loss of fluids and electrolytes — and certainly resulting in decreased power output. This only makes the power data we received from the race more impressive.

    Stage 1: Escondido (102.6 miles)

    During stage 1, the goal for many riders and teams was just to survive and finish the 100-plus degree opening day. Young American Chris Butler (Champion System) and Juan Antonio Flecha (Vacansoleil-DCM) were gracious enough to share their data from the stage.

    Results
    1. Lieuwe Westra, Vacansoleil-DCM
    2. Francisco Mancebo Perez, 5-Hour Energy
    3. Peter Sagan, Cannondale
    35. Juan Antonio Flecha, Vancansoleil-DCM
    39. Chris Butler, Champion System

    View Butler’s Stage 1 data in TrainingPeaks.

    Butler finished in the main bunch, just six seconds behind race winner Lieuwe Westra (Vacansoleil). Believing that the opening stage would likely finish in a bunch sprint, Butler’s goal was to stay with the GC contenders while conserving as much energy as possible for the demanding days to come.

    Stage summary (no speed or heart rate data)
    196 Average Watts
    3.2 w/kg
    239 Normalized Power (NP)*
    81 Average Cadence
    3160 KJ
    209 Training Stress Score (TSS)**

    *Normalized Power provides a better measure of the true physiological demands of an effort. It’s an estimate of the power you could have maintained for the same physiological “cost” if your power output had been perfectly constant rather than variable.

    **Training Stress Score quantifies the workload performed by a rider based on the duration and intensity of the effort. A 1-hour, all-out time trial effort would result in 100 TSS points.

    “It was incredibly hot today,” Butler said. “Perceived exertion was high. The only hard climb was the last Category 3 climb that lasted about 8 minutes, about 20 of us [went] over the top. It was so hot and I was so dehydrated every effort felt at least 50 watts harder.”

    Cole Grade was indeed where Butler set his 10-minute Peak Power for the day, averaging 347 watts (5.8 w/kg) and grinding it out at 75 rpm. During this effort alone Butler burned more than 200 calories, the equivalent of a gigantic, ice cold, 22-ounce Slurpee from 7-Eleven … the thought of which may have crossed some wistful minds during the long, hot day.

    The longest climb of the day, on Mt. Palomar, took Butler just over 44 minutes to complete. This is also where he set his 20- and 30-minute Peak Power values, averaging 268 watts (4.6 w/kg) and 250 watts (4.3 w/kg), respectively.

    With several more stages in the blazing hot southern California mountains, Butler will be looking to improve his GC ranking and show his climbing ability.

    Classics specialist Flecha also shared his data with TrainingPeaks. View his full power data here.

    Flecha is a very different type of rider than Butler. Butler is a young, aspiring climber and GC contender, while Flecha is a seasoned veteran, specializing in the classics and other one-day races. See a comparison of the two below.

    Flecha vs. Butler
    5-foot-11 vs. 5-foot-11

    3636 KJ vs. 3160 KJ
    204 TSS vs. 209 TSS
    286 NP vs. 239 NP

    As you can see above, the pair showed some similarities in their rides. Both finished with an official time of 4:31:39, just six seconds behind the stage winner. Both appear to have raced conservatively on the first stage, Flecha likely biding his time for an opportunity for a stage win later in the week.

    The similarities continue for many of the Peak Power values set on two of the three categorized climbs of the stage. Flecha also churned out his 10-minute Peak Power on Cole Grade and his 30-minute Peak Power (309 watts) on Mt. Palomar. Heading up Cole Grade, Flecha averaged 414 watts (5.5 w/kg) at a cadence of 79 rpm and an average heart rate of 167 bpm. The ascent of Mt. Palomar took Flecha 44:14 and he averaged 309 watts (4.7 w/kg), with an average cadence of 83 rpm and a heart rate of 150 bpm.

    Stage 2: Murrieta to Greater Palm Springs (124.3 miles)

    For stage 2, Saxo-Tinkoff provided race data from American and current national champion Timmy Duggan, as well as his Danish teammate Michael Morkov. Both are racing in support of team leader Michael Rogers.

    Results
    1. Janier Alexis Acevedo Colle, Jamis-Hagens Berman
    2. Tejay van Garderen, BMC Racing
    3. Philip Deignan, UnitedHealthcare
    34. Timothy Duggan, Saxo-Tinkoff
    59. Michael Morkov, Saxo-Tinkoff

    With temperatures of 120 degrees recorded on some riders’ bike computers and nearly 10,000 feet of climbing, stage 2 was brutal. The effect the heat had on performance can be seen through elevated heart rates. Many riders were riding at wattages much lower than their FTPs, yet their heart rates were at their threshold zones, resulting in a much higher rate of perceived exertion as described by Chris Butler in stage 1.

    See Morkov’s full power data in TrainingPeaks.

    86 Average Cadence

    As is the standard for many UCI ProTour stage races, an early breakaway was established and allowed to gain a maximum of 12:00 before Saxo-Tinkoff assembled at the front of the peloton and reduced the gap to 5:00.

    As a support rider, Morkov did his work leading up to the finishing climb, trying to protect Rogers for as long as possible. Looking at the file, it is easy to see where Morkov “pulled the plug” on the final climb after having done his job, reducing his power output and heart rate and settling into a steady pace to grind out the remainder of the brutally steep, 3.6-mile, 9 percent climb — an effort so taxing in the heat that many riders needed assistance after crossing the finish so as not to collapse. Some even required medical attention.

    The Amgen Tour of California marks Duggan’s remarkable return to racing on home soil after breaking his leg in a nasty crash at January’s Santos Tour Down Under.

    See Duggan’s full power data in TrainingPeaks.

    Duggan was on tap to position Rogers, who won the 2010 edition of the race, as best as possible on the final climb. When the fireworks started to go off, Rogers made the select group of five and would hold that position all the way to the line.

    Duggan spent the early part of the final climb guiding Rogers into position, and this is where he set his 10-minute Peak Power for the stage. Just as with Morkov’s file, we can clearly see when Duggan was working his hardest, giving 100 percent to his teammate until he had nothing left to give. Many people talk about the sacrifice teammates make for each other but to see it on these two race files is truly inspiring.

    The first two stages at the 2013 Amgen Tour of California showed some of the toughest athletes in the world enduring the “perfect storm” of melting heat and a challenging course. When looking at these numbers, reflect on the fact that the effect of altitude can be up to a 10 percent decrease in power output, but heat can do even more damage. Some riders had to abandon within the last mile or two of the finish. It doesn’t take numbers to prove that the pros are tough — but it certainly can help to illustrate.

    Editor’s note: Thanks to TrainingPeaks.com, we are looking at various riders’ power data from stages 1-2 of the Amgen Tour of California. Today, Shawn Heidgen, a USA Cycling certified coach, former professional cyclist, and Education Specialist at TrainingPeaks, recaps the data from the eight-day race.

  • Vacansoleil riders keep pedaling as sponsors depart team

    SANTA BARBARA, Calif. (VN) — The week opened beautifully for Dutch squad Vacansoleil-DCM. It earned a win and the leader’s jersey in stage 1 at the Amgen Tour of California on the legs of Lieuwe Westra, but it’s been tough news from there.

    Shortly after, second title sponsor DCM, a fertilizer producer in western Europe, announced it was leaving the sport. And then on Wednesday, Vacansoleil — the main sponsor of the ever-attacking team — announced it was leaving as well. This means the squad of Juan Antonio Flecha, Thomas De Gendt, and Westra, to name a few, will be without a sponsor at the end of the season. For riders at the races, there is little they can do but pedal and hope to fetch a result.

    “We’re proud. We have to thank Vacansoleil for the sponsorship, and we’re proud they achieved their goals. We’re happy for the sponsorship, we’re happy for that,” Flecha said before the start of stage 4, which ran from Santa Clarita to Santa Barbara. “And about the future, the team has the aim of continuing, and our team managers are already looking for sponsorships, and so on. We focus on our rides and our races. Personally, I’m not much concerned about it. It’s a good team structure, and it will work out.”

    Flecha departed juggernaut Sky in the offseason to heed his own riding style — always attacking, always opportunistic. He wasn’t regretting that on Wednesday.

    “I was willing to have a little more freedom in certain races. Especially after the classics,” Flecha said. “It’s a different way of racing. [At] Sky, the strategy’s always more focused on GC, on going for one guy in grand tours, and smaller races. And here, it’s different. It’s more going on the attack, taking different opportunities of course. We don’t have as big of guys for winning the GC as Sky, and I’m enjoying it a lot.”

    Asked if he would need to know if the team had a sponsor locked down soon or decide to leave, Flecha was calm.

    “I would say later. I’m focused as I say now on the races and Tour de France coming, and it’s not my job to try to find a sponsor,” he said.

    At his age and with his palmares, Flecha said he doesn’t feel pressured to notch results right now. “Not at my age — sorry,” he said.

    Westra, currently in the green points jersey in California, said the situation gives the riders more conviction.

    “Motivation? Yeah, for sure. I hope the team is going forward,” he said. “Yeah, yeah, yeah. The team is perfect for me. And I hope that next year I stay here also. Today is not good news. Both Vacansoleil and DCM have stopped.”

    The Amgen Tour of California continues Thursday, from Santa Barbara to Avila Beach, and for now, the Vacansoleil flag flies on.
