I’ve been looking at getting the Garmin 25 or the 520. I’m pretty minimalist in what information I need to know and won’t be adding a HRM or cadence sensors to it, so I was thinking more about 25. Maybe I’ll decide to splurge to get a few features that I might like at some point and some maps then I would get the 520. One thing I like about these units is the live tracking option. So my question is, has anyone with a Garmin unit capable of live tracking tried it during RAGBRAI and have any feedback? It obviously uses cell service to update where you are, and I know cell service is crappy at best, but would I be able to get service from enough towers along the route to keep updating the live tracking map? For now I have AT&T unfortunately. I want it mostly so my family members can watch my progress throughout the week, and RAGBRAI would be the only time I would use that feature. Thanks in advance for any feedback.
