With each jump, turn and hold left just before landing on the spikes, to get knocked back and down to the right, without damage boosting. Then turnaround spin jump to the right for the next jump. Jump can be held the entire time, to buffer the jumps. This method can be used while simultaneously carrying a blue suit and flash suit.
