There is quite a bit of testing done at lunch. It can take up to two hours or more sometimes. After all, testing is important.Trek factory visit by Guy Kawasaki.
...Trek staff heads out for the evening commute. Employees make good use of the commuter program. Each day someone rides, walks, skates or car pools to work, that employee receives credit for Trek products or cash for the cafeteria. This is an incentive to keep in the latest gear and promote general wellness. Between the commute to and from work and the “Lunch Time Ride” my friend at Trek used to average 50+ miles a day during the summers.
