RAAM Challenge Cycling Series Presents:

The Longhorn 500 and the Stampede 200 features the best of the famed Texas Hill Country.  It’s spring time in the Hill Country and the flowers – Blue Bonnets and Indian Paint Brush - will be blooming.  Temps are generally 50-80 F.  Mornings can be foggy with clearing by afternoon.  The event starts/finishes in Castroville, Texas, the Little Alsace of Texas, about 30 miles west of San Antonio.  Texas, the Lone Star State, is ranch country.


The 200 and 500-mile routes are roughly concentric loops, sharing the first 72 and last 63 miles. There are thousands of miles of paved winding ranch roads with little or no traffic.  You’ll experience some of the best cycling in the USA.

Both the 200 and 500-mile courses are moderately difficult - ideally suited to advanced beginning to intermediate level ultra-racers.

The Longhorn 500 and Stampede 200 are both part of the 6-event Texas Ultra Cup .

Coming Spring 2021!

  • The Longhorn 500

    The Longhorn 500 is challenging - 503 miles with 24,333’ of climbing.  The southern and western half of the route is within what is known as Southwest Texas – more remote, larger ranches, with several long steep climbs.  The northern and eastern half of the route is within the Hill Country. The 500-mile race is the first RAAM Qualifier road race of the domestic ultra-racing season.  It is also a great warm-up for racers and crew planning on doing RAAM in June.

  • The Stampede 200

    The 200-mile route is challenging - 195 miles with 8,399' of climbing. The course lies entirely within the Hill Country – many small ranches.  The climbing is distributed fairly evenly throughout the route.  Racers will ride unsupported, so there will be three aid stations on the route.
