Oooof, that's a tough situation.
Another toughy... I once again bungled me training and am suddenly being surprised by the Wings for Life World Run - I've written about it before somewhere around here*. As always, I'm aiming for 25 km total, but won't ever make it that far. Last year I managed 23.5, so close enough, but the last half marathon distance I've done was in bloody September! FFS. Let's see how far my legs take me...
I've done my homework at least in terms of route planning, starting out as high up as seems proper and sticking to pancake-flat-asphalt for most of the way. Then again, weather could screw it up. Temperatures are ok (~18-20°C), but himidity is a bit high (70%) and there's quite a chance of rain (more humidity). Also I don't really have any fuelling station... I'm thinking of bringing a bottle along and ditching it at the side of the road once I'm at a point that I'll be looping, but I'm not quite sure whether I'm too comfortable with that...
* huh, after going back 10 pages, I seem to not have done that after all? Or I didn't find it. It honestly is my favorite run, both because of the format as well as because it's (for me at least) an App-based run that I can just do on my own. I actually hate running in a crowd. I get that some (or even most) people get a motivational kick out of that, but I don't - I'm just annoyed by people not behaving properly (i.e. inexperienced people starting too far in the front of the pack, starting out way too quick, generally being in the way, not getting out of the way if you want to pass, and just behaving unpredictable).
it's an internal red bull sponsored thing with actual large scale runs / events in a bunch of cities across the globe. in addition, there's the app-run that happens at the same time in parallel to all the other runs. they all, worldwide, happen at the same time (today at 1 pm CEST) - so a bunch of people from the other side of the globe will be running at night lol.
now for the fun part, the actual format: there's no set target distance or time limit, but rather you start out running and after half an hour a catcher car will start following you (physical in real world runs, virtual in the app) slowly and continually increasing its speed (starting at 10km/h). once it catches you, your run is over. this translates to my goal of 25 km having to be run at 5:09 min/km pace and a total of 2:08 hrs. last year I managed 23 km at 5:17 min/km - so not too bad. and that was with a few minutes of walking at the end of the run because my legs quit on me, until then I actually managed to go target pace. this year: total toss-up. I fully expect my legs to just leave me somewhere around the 20 km mark.
Edit: alright that actually went better than expected…
edit2: global winner one japanese dude who actually managed to run 69 km in a little more than 4hrs. oof.
