Australian Rory Sutherland (Saxo-Tinkoff) continues to share his data with TrainingPeaks and VeloNews, most recently Stages 4 and 5 at the Giro d’Italia.

The Giro is known for its aggressive and gritty racing, and the first week certainly fulfilled that description. Lots of rain, technical routes, and mixed terrain made for an exciting week and some interesting time gaps.

However, Saxo-Tinkoff has been laying low, biding its time for team leader Rafal Majka to make his mark in the high mountain stages. Sutherland has been by his side, guiding him safely to the finish every day.

Stage 4: Policastro to Serra San Bruno, 246km

Results
1. Enrico Battaglin, Bardiani Valvole-CSF Inox
2. Fabio Felline, Androni Giocattoli
3. Giovanni Visconti, Movistar
53. Rory Sutherland, Saxo-Tinkoff

During Stage 4, Sutherland and teammate Evgeny Petrov escorted Majka all the way to the top of the last climb, watching many riders fall off the relentless pace being set by the members of Sky. The final descent was wet and technical and resulted in several crashes, but Saxo-Tinkoff was able to get all its riders safely to across the line.

Sutherland hit his 30-minute Peak Power on the final climb of the day, where so many riders were dropped from the lead group. It took Sutherland 28:30 generating 430 watts (5.7 w/kg) to stay with the leaders, averaging 27 kph (17.1 mph) up the 12.7-kilometer (7.9-mile) climb.

Once he made it over the climb, the work was far from done though. In the final 6km (7 minutes of the stage) Sutherland punched it over 700 watts 7 times! He did all of this while averaging 343 watts (4.5 w/kg) and an average speed of 52 kph (32 mph)!

Stage 5: Cosenza to Matera, 203km

Results
1. John Degenkolb, Argos-Shimano
2. Angel Vicioso, Katusha
3. Paul Martens, Blanco
100. Rory Sutherland, Saxo-Tinkoff

*Training Stress Score (TSS) 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.

**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.

The first 170km of the 203km stage were flat, but the two climbs at the end of the mixed with another day of wet, slippery roads made for a chaotic and fractured sprint to the line. Argos-Shimano’s John Degenkolb earned the victory.

Saxo-Tinkoff continued with its plan of conserving energy and manpower in the first week of the Giro until the last 8km of the race. At this point, the team set a fast, steady tempo in an attempt to keep the field together and give its sprinter Daniele Bennati a shot at the win. Unfortunately, Bennati fell victim to the crash in the final kilometer and was not able to contest the sprint.

With two climbs near the end of the stage and several teams determined to see a smaller sprint finish, the second half of the race was quite a bit harder than the first half. Especially painful was the blistering pace on the penultimate climb (Montescaglioso). Sutherland worked hard to maintain contact with the lead group, putting out an impressive 502 watts (6.6 w/kg) for 8:30 while watching many of the sprinters fall to the rear of the peloton.
