I'm impressed at your doing a tri. with a broken spoke in 88 degree heat! With that kind of determination, you will do well with your weight loss.
I'm not really slim or stylish, but believe in the power of speaking into reality what you want.
I've been struggling with weight since I was 9 years old. Fortunately, found cycling in 1982 and weight has been stable within 10-15 pounds, but NEVER got to my ideal weight. Sparkpeople has given me the tools with giving me my BMR calorie range, mealplanner, and exercise tracker. In 45 days I lost eight pounds.
Keep riding, it's the best fun recreational, sport, utility activity!
