In cycling, it's evident that EPO had a huge impact, but that the peloton slowed after Festina (and the EPO test). It gained ground again until Puerto, but didn't reach the EPO speeds. Then it was at its slowest from the passport to the pandemic. We have good measures of the peloton's speed, and we can point to what managed to slow it down.I'm honestly not sure that any footballers are putting in physical efforts that compare to even 6 w/kg for 30 minutes, let alone what Pogacar and co do. To go back to McTominay, he was someone who could run a 34 minute 10km as a teenager (nothing outrageous), has put on muscle, and now does a 16 minute interval 5k (so between 17 and 18 min 5k if flat out). This isn't an absurd level of physical performance, and he's considered to be the fittest player at Manchester United.
The current peloton remains, on available evidence, well ahead – at least, I don't think there's much evidence outside of vibes to suggest that cycling 'slowed down' relative to football. If there is some, would be happy to be pointed in that direction, but the fitness level of Premier League footballers to me does not appear as ridiculous as what the peloton has been doing since 2020.
Comparing the physical efforts of football with cycling is very tricky. First of all because it's not an endurance sport that is about such efforts. Rather than doing a direct comparison of the two sports today, I find it more illuminating to compare the trajectories of the two sports. We know football players used EPO, we know they used blood bags. Afaik, Fuentes had more football business than cycling business. Did football slow down after Puerto? Did football get the same anti-doping treatment afterwards that cycling did? Afaik, there's nothing to suggest that football players became less fit afterwards.
