Bruh how can i get into mid 100s speed (biglad69)

Up before daybreak, but still not early enough, as the Imperial Light Horse and a battery of Natal Artillery had already gone towards Elandslaagte, about sixteen miles from here, at three o'clock. It was bitterly cold when we started, and for a couple of hours of our journey. About half a mile beyond Modder's Spruit Station we met a man walking along the road in his socks, carrying a pair of heavy boots. He told us he had just escaped from the Boers, after having been, with thirty other miners, their prisoner since Thursday last. His feet were sore from running in the big boots, and he was nearly exhausted.
