Hard to compare because the magnetic resistance gets harder the harder you push.
On 1 I can sprint the sled, comparable to an empty metal sled. On 2 I can still sprint it a short distance but it feels heavy. On 3 I can push fast for a short distance, but it feels really really heavy.
@cringe Sounds like a lot of fun anyways.
@cringe Do you have any comparison of the resistance to a "normal" weighted sled?
