are you doing strength training?
what is your current diet?
Are those your current stats listed in your signature?
truthfully probably not. When running you have to support your full body weight in the movement making it harder (note your heart rate after your next session), where as with cycling as you are generally sitting down so you aren't supporting your body weight making it easier (again check your heart rate after this and compare to running heart rate).
That all said truthfully it fully depends on what your goals are
