Two magnets don't work. LOL. My mechanic forgot to take the front one off when he installed my new wireless computer last week. Totally messed up my readings when I went for a ride the next day.

What's helped me is time and learning to not stress my entire ride about it. If I'm relaxed I can pedal better and move faster.

Challenging yourself also helps. Last week my DH called asking if I wanted to go to Omaha with him and I had gone to Lincoln earlier to ride one of the trails. He caught me at mile 9 and I knew I had to make it back to the car ASAP. I was doing a nice steady 10mph and headed back at 15-18mph until my body started protesting about 4 miles from the car. I didn't know I was capable of moving that fast even though it wasn't for very long.
