Armstrong competed on home ground in the Tour of California last month
Seven-time Tour de France winner Lance Armstrong will continue his comeback with a return to Europe this month.
The 37-year-old American will compete in the Milan-San Remo one-day race on 21 March, followed by the Tour of Castille and Leon from 23-27 March.
The Spanish race will allow Armstrong to focus on the time trial and two mountaintop finishes.
Armstrong returned to competitive cycling in January after retiring three-and-a-half years earlier.
He took part in the Tour Down Under in January, and the Tour of California in February.
