A third day of racing was added, and the race dropped Madrid from the title to become the Challenge by La Vuelta as stages were held outside the borders of the Autonomous Community of Madrid. The rescheduled 2020 edition consisted of 2 short stages and an individual time trial. As with previous editions, the final day of the race coincided with the final day of the Vuelta a España.
The race was increased from two stages in the past two editions to three this year, which race officials cited was due to the "uninterrupted growth dynamic that has maintained since its creation." The race started with a 83 km (52 mi) hilly stage from Toledo to Escalona, followed by the traditional 9.3 km (5.8 mi) individual time trial in Boadilla del Monte. The final stage was a 100.5 km (62.4 mi) criterium in Madrid that used the same finishing circuit that was used for stage 21 of the 2020 Vuelta.
