Based on these texts, what is the recommended diet for marathon training?

These passages do not provide guidance on diet or physical training for athletic events. The focus of Chapter 51 is on the spiritual journey and the subtle ways Sai Baba guides his devotees. The story highlights a series of happy coincidences for Kakasaheb Dixit: receiving a cherished portrait of Baba at the perfect moment, finding a seat on a hopelessly crowded train through an acquaintance, and then unexpectedly meeting another devotee, Nana Saheb Chandorkar, upon arrival. These events filled Dixit with joy and reinforced his faith.
