Brief summary: This trial is conducted in Europe. The aim of the trial is to compare the effect of exercise on blood glucose in subjects with type 1 diabetes, who are treated with either insulin degludec (IDeg) or insulin glargine (IGlar).


Eligibility criteria: Inclusion Criteria:

* Type 1 diabetes mellitus (as diagnosed clinically) for at least 12 months
* Body mass index 18.0-27.0 kg/m\^2 (both inclusive)
* Subjects performing regular physical cardiorespiratory activity
* Glycosylated haemoglobin (HbA1c) below or equal to 9.5 %

Exclusion Criteria:

* Subject who has donated any blood or plasma in the past month or more than 500 mL within 3 months prior to screening
* Smoker (defined as a subject who is smoking more than 5 cigarettes or the equivalent per day)
* Not able or willing to refrain from smoking and use of nicotine substitute products during the inpatient period
* Supine blood pressure at screening (after resting for at least 5 minutes) outside the range of 90-140 mmHg for systolic or 50-90 mmHg for diastolic

Primary outcomes:
measure: BGpre-exe - BGminimum,exe, difference between blood glucose concentration before exercise and the minimum blood glucose concentration observed during exercise
timeFrame: From 0 to 30 minutes
Secondary outcomes:
measure: BGmean,exe, mean blood glucose concentration during exercise
timeFrame: From 0 to 30 minutes
measure: BGmean,30-180min,post-exe, mean blood glucose concentration
timeFrame: Between 30 and 180 minutes, i.e. post-exercise
measure: BGminimum,30-180min,post-exe, minimum blood glucose concentration
timeFrame: Between 30 and 180 minutes, i.e. post-exercise
