    • Enter or confirm that the Traveler's name, employee ID, email and phone number are correct.

  3. Indicate whether your trip includes personal travel.
  4. Click "Save & Next."

    • If you include an estimate for "Other Costs", you will need to specify these estimated costs in the Purpose and Justification section of the request.
  2. Click "Save & Next."
  1. Enter the business purpose of your travel. Be complete when explaining how the travel benefits the project (if using a sponsored award to support your trip) and include the full name and titles of papers if you are attending a meeting. Please do not use acronyms.
  2. Click "Save & Next."

CIRES employees or students travelling within the state of Colorado for a single-day meeting, workshop, or field work do not need to submit a travel request in InsideCIRES. If the university is only covering the cost for a conference registration fee, a day of mileage/rental car, please email CIRES Travel after the trip to coordinate any reimbursement. Traveler may receive per diem on single-day trips if the business day lasts 12 hours or more. Travelers should submit a travel request for prior approval if in-state travel costs will include typical travel expenses (i.e. overnight lodging, daily per diem, parking fees and/or mileage).

Non-employees receiving support for travel from CIRES should complete the Non-Employee Travel Request form and submit the request to cirestravel@colorado.edu. Detailed information about non-employee travel is available and can be downloaded from CIRESConnect here.
