Climbs and Time Trials

Every year the presentation of stage races courses bring discussions on whether the path is more suitable for pure climbers or rouleurs-climbers.
In an attempt to propose a criterion based on numbers and not just opinions and clichés, I would like to express some considerations.
Most of the route of every stage race takes place on the flats and relatively easy hills (with average slopes of less than 7%): drafting gives significant advantages in both cases, advantages that are difficult to quantify and that differ from rider to rider (athletes of small size, in any case, have a greater benefit than bigger athletes).
I shall therefore compare typical time trial courses with climbs of an average gradient superior to 8%, where speed is reduced, making the advantage of drafting of little significance.
I calculated the difference in speed, on flat course and uphill, corresponding to a difference in required power equal to 5%:
- pedaling at 51.2 km/h on the FLAT requires 5% more power than pedaling at 50 km/h
(2625 vs 2500 are the square speeds): the difference between them corresponds to 1.7”/km, equal to 1.4”/min of effort.
The same happens even at lower speeds: pedaling at 41 km/h requires 5% more power than at 40 km/h (1681 vs 1600 are the square speeds): the difference corresponds to 2.2”/km, equal to 1.5”/min of effort.
- pedaling at 20km/h UPHILL requires 5% more power than at 19 km/h: the difference between the 2 speeds corresponds to 9.5”/km, equal to 3”/min of effort.
The same happens at lower speeds: 15.8 km/h and 15.0 km/h present a difference of 5% in required power output, corresponding to 12"/km and 3"min of effort.
Therefore, it is more difficult to make the difference in a time trial event than on a climb: a 5% gap between 2 athletes will be half as advantageous on a flat course compared to a climb.
In other words, an uphill finish (with an average gradient higher than 8%) of more than 30 minutes in duration is compensated by a flat course time trial of 60 minutes."
"Where are the Stage Races going?

In the last few years we have seen how the dominance of certain teams greatly conditioned the name of the final winner in the most important stage races.
The strength of such teams has been so dominant that it's been rather easy for them to control and determine the sequence of events during the most crucial stages, imposing such a high pace as to discourage and "clip the wings off" those riders fighting for the general classification and brave enough to attack early in the race.
All of this with the goal of preparing the ground for the attack of their captain/s just a few km from the finish.
We have indeed witnessed the extolling and triumph of aerobic POWER over ENDURANCE.
The same could be said about time trial stages, rarely longer than 30-50 minutes and ever more specialized: either for high-powered rouleurs or very light climbers.
I remember some editions of the TdF with time trials of 70-80 Km on tough courses with proper climbs and technical descents which could really show all the skills of the riders, especially endurance, intended as the ability to sustain a high effort for 90-120 minutes.
In a cycling scene that resembles all too much the same, without original ideas, made inflexible in its obsessions, it might be very interesting to propose a hard stage towards the end of the 3 weeks exclusively raced by a single rider per team.
While the rest of the peloton is being neutralized, the designed leaders (finally!) would face each other directly in the ultimate endurance test, where those able and brave enough to try, can be able to attack far from the finish in an almost individual confrontation."
Specialization in cycling and complete riders

In the last 30 years of cycling, 20 riders were able to win at least a 3-week stage race (TdF, GIRO, VUELTA) and at least one "Monument" Classic
(Sanremo, Flanders, Roubaix, Liege, Lombardia , World Championships).
In the last 10 years, only CUNEGO (Giro, Lombardia), VALVERDE (Vuelta, Liege), VINOKOUROV (Vuelta, Liege) and DI LUCA (Giro, Liege, Lombardia) managed the feat.
In the 90's, BUGNO (Giro, Sanremo, Flanders, World's), ROMINGER (Giro, Vuelta, Lombardia), BERZIN (Giro, Liege), JALABERT (Vuelta, Sanremo, Lombardia), OLANO (Vuelta, World's), ARMSTRONG (TdF, World's).
In the 80's, FIGNON (Giro, TdF, Sanremo), ROCHE (Giro, TdF, World's), HINAULT (Giro, TdF, Vuelta, Roubaix, Liege, Lombardia, World's), MOSER (Giro, Sanremo, Roubaix, World's), SARONNI (Giro, Sanremo, Lombardia, World's), LEMOND (TdF, World's), KELLY (Vuelta, Sanremo, Roubaix, Liege, Lombardia), MARTENS (Vuelta, Flanders, World's), ZOETEMELK (TdF, World's), POLLENTIER (Giro, Flanders).
It's easy to see how the number of riders able to excel at both types of events decreases over the decades.
In my opinion, there are several explanations.
The level of competition in the CLASSICS has increased steadily over the years, with more and more athletes aspiring for victory than in the past. This determined an exasperated specialization and finalization in training and racing calendar planning.
The same happened for STAGE RACES, with specialists focusing their efforts almost exclusively to the preparation of the grand tours.
Undoubtedly, the PSYCHO-PHYSICAL demands of a classic 1-day race are very different than those of a stage race, thus selecting those riders that are more suitable to violent efforts, rather than endurance and recovery skills.
THE COURSE characteristics of Classic races changed very little over the years, while stage races (especially Giro and Vuelta) decidedly designed the courses in favor of light riders, multiplying the number of uphill finishes and extreme climbing gradients.
This determined that riders suitable to stage races have been trying to reduce their body weight as much as possible, to the detriment of the absolute power necessary to excel in the Classics.
