Official TCS London Marathon

★★★★★ The app was accurate to the mileage and I enjoyed the live commentary during my recent virtual London marathon hope we can get another chance to run the virtual London again it was a enjoyable experience.

★★★★★ Really good app easy to use....made the race more exciting being able to follow our two friends

★★★★★ I'm using it to run the 2021 virtual marathon... just tried it today for the 5km test run and it all worked well. Looking forward to Sunday's proper race!

★★☆☆☆ why did my daughters virtual London marathon app say 26.2 miles when mine said 25.2 (as did my garmin forerunner) when we both started app same time and ran together through out? I had to run an extra mile. This is not acceptable.

★★☆☆☆ The good: It didn't eat up my phone battery. In fact I had this, WhatsApp location tracking and Garmin LiveTrack running on my phone, and more than 6 hours later I still had 40% battery left. Not bad for a 3 year old phone. The bad: It was a waste of time installing it. I upgraded it to 4.1 the night before the marathon, which didn't inspire confidence. Then reading about all those in time zones ahead of us, and those mad enough to start at midnight in the UK having problems with it, inspired even less confidence. At the start line, I started my Garmin Watch and then press Start My Run in the app, and started to run, only to notice it then needed permission to use my location, so I headed back to the start line and did it all over again. It was when I surprised someone at a drinks stop at 21 miles that I realised something was up, as she'd been tracking me and it said I was at 19 miles. When I finished, my Garmin said 26.29 miles which was correct as I'd cycled the route previously to make sure, and I looked at the app and it said I'd done 24 miles. No chance I was going to walk another 2 miles so I just ended my run. I didn't even need the app to upload my run, the instructions came through by e-mail and I just connected my account to Strava on my PC. At least that part was easy. All in all, it was clearly a rush job due to the circumstances, which I can understand. It didn't affect my walk in any way but I'm sure there are others who were using it as their only proof of completing the distance, and who would have been very disappointed.
