Tour de France champion Lance Armstrong (above) has teamed up with some real estate veterans to raise $100 million to buy up commercial space in central Texas. Armstrong — who battled testicular cancer and dated Sheryl Crow, Ashley Olsen and Tori Burch — already has offices in Austin for his Capital Sports & Entertainment Holdings and C3 Presents, which produces Lollapalooza and the Austin City Limits Festival. The new venture, CSE Realty Partners, includes former Trammel Crow executive and Denver Broncos wide receiver Patrick Jeffers.
