What racers and reviewers say
- Suffolk TimesRaced 2018 · article · Mixed
2018 profile of a 64-year-old first-timer with Parkinson's racing alongside her partner, the race founder. Race started at Cedar Beach before sunrise in dark clouds, strong wind and icy rain, called less than ideal. Shows the race welcomes first-timers; weather in late May is a gamble.
