Mallorca 312: Wish Me Luck (200 miles, 5,000m, one day)
Just heading off to Mallorca for the 312 Gran Fondo.
Thousands of crazy cyclists embarking on a 200-mile, closed-road, one-day hill fest. Well, mostly one hill, although the total ascent is about 5,000m. That’s Mallorca 312.
200 miles is pretty hard in itself, as I found on Chase the Sun (CTS, 2024) a couple of years ago, but if you can do 100 miles, you can do 200. In prep for CTS, I did back-to-back 100 milers, and I did the same last week. The differences this time around: two years older, a worse rental bike than my excellent Cervelo S5, and 5,000m of climbing (yikes). On the positive side, the gradients should all be manageable, the road surfaces excellent, and there should be plenty of drafting opportunities to save the legs.
Whatever happens, it isn’t going to be easy, that’s for sure.
The route seems to go past DC Rainmaker’s house. No doubt he’ll be out cheering me along (maybe). I was going to re-test the Huawei GT Runner 2 on his switchback route where he got some errors, but a) it’s 50 miles from where I’m staying, b) I might be a wee bit tired, and c) I know why the results were different in any case 😉

Good luck!
Interestingly, the map you have above does show it passing relatively close to my house, but the 2026 route published on their site currently keeps fully within the mountains on the west side instead. So…further away from my place.
As a side note on the GT Runner 2 results, they did actually come back to me last month with their results after they sent a few engineers there to run it a gazillion times up/down (poor guys). TLDR: The ‘Run’ mode didn’t handle any inclines/hills correctly, and caused the GPS issues I saw. If you were in ‘Trail Run’, it handled fine, but regular run basically broke all hills from a GPS standpoint (hence why I also saw the issue on road running with hills). They were planning a firmware update the last week of March, but I haven’t been home much in the timeframe since to re-test.
Speaking of which, I sadly won’t be home this weekend either, but halfway cross the world. Have fun though!
