Final answer:
The query appears to inquire about historical figures noted for extensive horseback riding. Specifically identifying the individuals who have ridden the most miles on horseback is challenging due to the lack of precise historical data, and the mention of characters like Jane Withersteen and Venters suggests a fictional context.
Step-by-step explanation:
The question pertains to historical figures known for extensive horseback riding. Although specific historical records on this topic may be scarce and hard to verify, we can look at individuals known for their significant horseback journeys or roles in societies where horseback riding was prevalent for transportation or military purposes. For example, the Mongol messengers during the Mongol Empire covered immense distances on horseback, with the empire's postal system relying heavily on relay riders. Another example could include the Spanish conquerors, like Hernán Cortés and explorers such as Coronado and de Soto, who introduced and utilized horses extensively in the Americas.However, without clear historical evidence, proposing a definitive main answer to who rode the most miles on horseback is speculative. The passage mentions characters like Jane Withersteen and Venters, which seem to be from a literary source rather than historical accounts. These characters could be part of a fictional narrative that emphasizes the significant role of horses in frontier life.In conclusion, to identify the person who rode more miles on horseback than any other person, with someone as second, would require extensive historical research, and it's important to discern between historical figures and characters from literary works when exploring such a topic.
