Hello!
Our NGO (https://www.bartali.org.il), is organizing a "challenge" this weekend, in support of the children who lost their families in the war in Israel on October 7th.
I would like to ask what is the best way to set up such a challenge on Strava, so people could log-in the miles they are riding, where ever they are (either from their Garmin or from ZWIFT) and it will all be summed on one dash board.
Would truly appreciate your prompt help!!
