Many events say to “sign-up early,” but that’s essential advice when it comes to the 31st Annual Mercedes-Benz Corporate Run Miami on Apr. 28. Last year’s event sold out with almost 38,000 runners and 1,300 South Florida companies registered. Think your company is too small? Teams range from 4 employees to over 2,500. Runners and walkers of all abilities are welcomed at this health- and wellness-focused 3.1-mile road race/walk where, unlike other running events, there’s no individual scoring. Instead, the focus is kept on office solidarity as teams compete within industry categories. Many companies rent team tents to serve as meeting spots and celebration points. Open to employees of corporations, government agencies and financial institutions. Registration closes on Apr. 23; MercedesBenzCorporateRun.com.
