Transitioning from running outside to running on treadmill?
I've been running outside since July and ran my first 5k race in December (yay!!) well I was tired of dealing with crazy low temps and ice so I joined a gym. However I am having trouble running on a treadmill. I feel wobbly when the speed gets over 4.5. Is this normal? Or is it just me? Or do I need to just keep doing…
