Conduit sharing 120 vac & 240 vac

From the main panel, I want to drop a 120 vac circuit from its own breaker, and a 240 vac circuit from its own breaker... then run them both in a common conduit (30 - 40 feet) to a box, where the 120v will branch off to its final use... the 240v wiring will continue on to a sub-panel. Is it OK to run these two sets of wires together in the initial length of conduit?

Provided that 40% conduit fill is not exceeded, derating is calculated, and neither circuit is used to power a pool, spa or similar installation; your plan is acceptable.

Please make sure you run a 4 wire feed to the subpanel. Two hots, 1 neutral and a grounding conductor.
