I believe in keeping running simple and, in regard to shoes, that would mean no gimmicks, unnecessary cushioning, etc
I believe in gradual experimentation with running shoes.
I believe you'll develop speed via strength work which includes hill running, either repeats, or running hilly courses as the Kenyans do on a steady basis
I do believe eating "smart" will lead to superior efforts over the long haul.
I believe 100 per cent in continued running after 40, and racing too, if one so desires.
I believe in light shoes for every runner.
Of course, today everything is records and times, but I believe the greatest marks are setting not only world and other records, but achieving success in different weather condition and competing in major championships; in other words facing the competition fairly in all venues.
