Distance Calculation: Converting 1 km and 1000 m in Daily Exercise

Let's proceed with the solution:

Step 1: Convert running distance from kilometers to meters.
Since $1 \text{ km} = 1000 \text{ meters}$, the running distance is $1 \times 1000 = 1000$ meters.

Step 2: Add the walking distance and running distance to find the total distance.
Total distance = Walking distance + Running distance.

Walking distance: $1000$ meters.
Running distance: $1000$ meters.

Therefore, the total distance traveled each day is:

$1000 \text{ meters} + 1000 \text{ meters} = 2000 \text{ meters}$.

Thus, Darrel travels $2000$ meters each day.

Please note, the original question presents these as integer values, and there might be a mismatch due to a contextual issue. However, based solely on the given data, the computed total is $2000$ meters.
