During his career in Outdoor Adventure Education he also was an instructor at DoDDS's Project Bold, located at the Hinterbrand Lodge in Berchtesgaden, Germany. Afterward, Udall served as Outward Bound's Executive Director for ten years, after which Udall decided to retire, completing his twenty-year career with Outward Bound.

In 1996, Udall was encouraged to run for the Colorado House of Representatives by Peggy Lamm of the 13th district, who had decided to retire.{{cite web|url=https://www.mensjournal.com/gear/mark-udalls-toughest-climb-20131127|title=Mark Udall's Toughest Climb|first=Bill|last=Gifford|work=Men's Journal|date=November 2008|access-date=August 25, 2024|archive-url=http://web.archive.org/web/20100310162334/http://www.mensjournal.com:80/mark-udalls|archive-date=March 10, 2010|url-status=live}} After running a grassroots campaign in the swing district, Udall narrowly defeated Republican Drew Bolin to represent the Longmont and Boulder district.{{cite web|url=http://www.ciruli.com/view4.html|title=The Ciruli View|date=October 1998|work=Ciruli Associates}} During his two years in office, Udall served on the Judiciary and Agriculture Livestock & Natural Resources Committees.{{cite web|url=http://www.leg.state.co.us/lcs/leghist.nsf/736b5262efff1c5087257751006d4155/5966f9c9e69da1f6872578e20063bcae?OpenDocument|title=Legislator Record|work=Colorado General Assembly}}

While in the Colorado House, Udall proposed legislation titled "Renewable Electricity Standard." It would have required at least 10% of energy consumed in Colorado to be provided by renewable sources rather than fossil fuels. The bill died in committee. Udall chose not to run for re-election, instead decided to run for the United States Congress. He was succeeded by fellow Democrat, Tom Plant.

After one term in the Colorado House of Representatives, Udall opted to run for Colorado's 2nd congressional district, which was being vacated by incumbent David Skaggs. In the primary, Udall had four opponents: Gene Nichol, Paul Weissmann, and Dave Thomas. He won with 44% of the vote, defeating his closest opponent Nichol by 7 percentage points.{{Cite web|url=http://www.cnn.com/ALLPOLITICS/1998/08/12/primary.results/colorado.html|title=Colorado Primary Results – Aug. 11, 1998|publisher=CNN|access-date=August 25, 2024|archive-url=http://web.archive.org/web/20000819020608/http://www.cnn.com/ALLPOLITICS/1998/08/12/primary.results/colorado.html|archive-date=August 19, 2000|url-status=live}} He faced the Republican nominee, Boulder, Colorado Mayor Bob Greenlee in the general election. The race was unexpectedly close, with Udall narrowly winning, 49% to 47%. Udall was consecutively elected to five terms in the House, without major opposition. He was eventually succeeded by Jared Polis, after he decided to run for the Senate seat being vacated by retiring Republican Wayne Allard.

Udall's re-election campaign focused on reproductive and women's rights.
