I finally took my bike with me and rode on a work road trip. Was a really nice ride, going south out of Billings MT for about 10 miles, while climbing about 900 feet, then returning on the same route. Temperature was 85 at the start and 79 when I finished. Dry and sunny, a gloriuos day! On the way to Billings, I ate at the Golden Arches place, about 2 hours before my ride. Where I would normally start a ride after pumping tires and all that with a HR of about 100-110. Today, shortly after eating I felt quite anxious, and jittery. When I got on the bile my HR was 140. I felt good during the ride, but my HR was through the roof. I have self tested my HR on big long hills at 194. today I hit 196. My LT is about 176, today it was in the mid 180's based on respiration rate. Finally at the end of the ride it started returning to normal, and as I write its less than 100 bpm, which is typical for sitting and typing.
What gives? the only time I have experienced anything like this is certain fish sticks really cause my heart to race. Perhapes is sulfites? Any thoughts/experiences?
