It does also fit the theme because Igor Arrieta raced against Oscar Sevilla in the 2022 Spanish Championships after his father raced against Sevilla plenty of times over the course of 10 seasons.
Luis Leon Sanchez also raced against Igor in about 20 race days in 2022 and 2023 after racing with Jose Luis for Seven seasons.
Plenty of other riders as well who were pro in 2010 and 2022, Even Ion Izagirre who was in the 2010 Gran Premio Miguel Indurain
I managed to find almost 100 other guys who also raced with or against both Arrietas.
Here they are in no real good order.

Pozzovivo was in the 2005 MSR with JL Arrieta where he was defeated, taking 163rd against Arrieta‘s 126th. Thereafter, their race schedules caused them to not meet for over five years, allowing Pozzovivo to plot his revenge, which he would exact in the 2010 Giro del Trentino. Pozzovivo went on to win the Final Stage in that race while Arrieta did not ride to the finish, thereby asserting Pozzovivo‘s superiority.
