The first lead boat race – the Lidville 100 and the SBT GRVL – took place last weekend, and the two-day, 400-km combined race won the first men’s and women’s championships. Keegan Swinson took control of the Livville 100 on Saturday, beating Lachlan Morton in about eight minutes. But on Sunday, when Alex House defeated Ian Boswell and Peter Stetin by three speeds, the (former) street contestants got their revenge.

In this column we will look at the power numbers from both races, and see how each race is determined by the combination of high altitude, quick decision-making, and pure strength.

I don’t write mountain bike articles very often — this may be my first mountain bike power analysis — but the Lidville 100 is worth a closer look. If you have watched any Olympics, you may be expecting a 1-2 hour race with some steep hills and rocky hills. But Lidville 100 is a completely different animal.

The 2021 Lidville 100 is 105 mm (169 km) long and stands at 11,800ft (3,600m). If the profile of the road is not good enough, it really hurts one. Starting at 10,000ft (3,000m), the Lidville course climbed to the top of Columbus at the top of the quarter to 12,500ft (3,810m). The 73-kilometer entrance to Columbine was easy: even though he was still with the front team, Swinson held more than 4 watts of normal power for two and a half hours.

At each climb, Swinson pushed 300-400w (4.5-6.1w / kg), then lowered down the coast. But when it comes to technical skills, mountain biking requires more than road racing. Horsemen roaming the dirt, gravel, and rocky roads. The ban will have some effect, but the upper body will do a lot more work for Pogarga while digging the Monta Ventu.

In almost half of the race, Swinson and his team beat Mount Colombia, averaging 8.9 percent, averaging 8.9 percent. There were more than 13 percent long curves, and the road was not closed. Nearby, Swinson was driving at a speed of more than 5 watts and a straight 13 percent section of 6 m / s (9.7 km).

Swinson – Columbine:
Time: 49:22
Average power 308 watts (4.7 kg)
First 1.8 km (average 8.3%) 331 W (5 W / kg) for 7:45
Last 1.8 km (average 11.8%) 290 watts (4.4 watts) for 12:07

Don’t let these numbers fool you – Keegan Swinson is not as strong as professional road drivers. Crazy heights (over 10,000 feet) have caused huge losses to athletes’ performance, especially in the event of long hours of endurance. A lot of people had to ride on top of Columbia, but Swinson still managed to turn the pedals over 4 watts.

Leading teams – Swinson, Morton and Olympique Howard Grots – went down to Colombia and continued to the final junction of the course – Powerline. At an average speed of 6 km at 7.6 percent, Powerline was not as heavy as Columbine, right? Well, the ladder has a few steep slopes, and more than 20 percent have multiple sections.

Swinson made his winning streak on the Powerline and killed about 6w / kg on the 9500ft to 11,000ft road.

Swinson – Powerline:
Time: 26:39
Average power; 314 watts (4.8 kg)
Normal power; 324 W (5 W / kg)
First Kilometer (Average 14.2%) 347 W (5.3 W / kg) for 6 25

After Powerline went down, Swinson was in TT-mode, like a metronomy pedal, and dropped his offspring as much as possible. On the way and to the end, he still pushed 320-350 watts (4.9-5.3w / kg) on ​​his bike and put it in the chase for minutes.

At the top of the Powerline, Swinson had already reached the race five hours, burned more than 4,500 KJ, and earned 300 TSS. Most of us have never traveled that far. But Swinson did not diminish much.

Swinson – Power line to complete:
Time: 1:02:27
Average power; 249 watts (3.8 kg)
Normal power; 282 W (4.3 W / kg)
Lake Turquoise Exit (Average 4%) 322 watts (4.9 watts) for 12:03

Swinson’s permanent government power was reduced by 10-20w in the last 20 km. But again he had an eight-minute lead. Finally, Keegan Swinson took full control of the Lidville 100 with a power file that looked directly outside the World Tour.

Swinson – Lidville 100:
Kilometers: 169.4
Time: 6:11:54
Average power; 250 W (3.8 W / kg)
Normal power; 285 watts (4.3 watts)
Burnt power; 5587 KJ
Gain height; 3,654m (11,988ft.)

Less than 100 farms lined up for the SBT GRVL in less than 18 hours after completing the Lidville 100, one of the world’s largest pebbles, covering 141m (227km) and 9,840ft (3,000m). Among them were Peter Stetina, Alex House, Freddie Oveet, Ted Kind, Colin Strickland, Adam Robberge, and unbeaten champion Ian Boswell.

Unlike the Lidville 100, the SBT GRVL has no major hills. Instead, the course covers endless sections of rollers, ladders, and corners. The 1,500 field decreased during the day, and eventually less than 10 horsemen remained. One of them was Stina, who had just finished fifth in Lidville the previous day. Take a look at one of the power files from SBT GRVL, and we will see a well-known graph.

SWISSON – First 70 km:
Time: 2:05:54
Average power; 228 W (3.6 W / kg)
Normal power; 269 ​​W (4.3 W / kg)
Climbing at Kilometer 46 (average 6.6%) 321w (5.1w / kg) for 8:50

During the first two hours of the race, the state average was tenth of a second from Swinson Watt-Kilo. Both courses had the same opening ground to start, and while the team was still 100 horsemen strong, overall flexibility was in play.

For the first few hours, the only challenge was to climb 57 km, and State only weighed more than 5 kg. At the top of the mountain, it was pushing more than 350 watts (5.5 watts) to lighten the front team. While these numbers may not be impressive, remember that we are 8,000ft (2,400m) high.

For the next two hours, the race was relatively calm. Estina spent an average of more than 200 watts (3.1 watts) on the beach. Of course, the gravel roads around Steamboat Springs were not very much a hobby, but compared to what they could, these (former) WorldTour pros made it much easier. As the road slowly descended to the Pinnacle Peak, the race was over 100 miles[140 km]. Stitina – feeling the effects of the day – admits that she is not in good condition, and she sucks as much tires as she can to survive. Even so, state records show that he was one of the strongest horsemen of the day.

Estonia – 140 to 167 km:
Time: 59:06
Average power; 243 W (3.9 W / kg)
Normal power; 262 W (4.2 W)
Last 1.9 km (average 5.7%) 331 W (5.3 W / kg) for 5:09

After five hours in the saddle, he won the SBT GRVL Finals in the second day of the race. As he left Oak Creek, the team hit the first field. Estina stepped forward, and the others began to retreat.

Statina – Oak Creek exit:
Time: 6:44
Average power; 312 W (5 W / kg)
Normal power; 327 watts (5.2 watts)

The next climb came at km 201 and almost every rider in the group. It was amazing to see more than 300 watts of horseback riding. The state-of-the-art capacity of 5w / kg for five minutes is world-class.

STATINA – Downhill at 201km:
Time: 4:38
Average power; 351 W (5.6 W / kg)

The last climb of the SBT GRVL came a few miles later, and although it was not as steep as before, it was just as bad. Stetina was still able to push around 5.5 watts and had the power to run at 13 watts.

STATINA – 206 km final climb:
Time: 5:46
Average power; 314 W (5 W / kg)
Normal power; 325 W (5.2 W / kg)
High power: 813 W (13.1 W / kg)

The fact that the last 13 km was flat does not mean it was easy. In fact, these last 17 minutes – coming more than six hours into the trip – have been Stetina’s strength all day. Pulling over 300 watts and climbing to a height of 400 watts, State was able to stay with him, putting pressure on Jose and Boswell.

In the final race, the three were together. One of the strongest of the day, pointing to himself, Stina pushed a few hundred yards to get to the front. Boswell came around, and House also, the former American road race champion, won the SBT GRVL. Statina finished third in the race, and did more than enough to win her first LeadBoat title – all in one day, average and normal power that looks very similar to what Swinson’s 100 days in Leidville.
