Oh Dear
This is always awful news to read - but somehow worse when it is someone you have connections with... Hugs from another TE-er (gentle ones).
I take it you have no breaks? You both just sustained bruising and cuts? I guess that is good because it is less time to heal, but all of us here know it is more than just physical healing.
Awful to hear about your bike too. I have sat with several people who have come off their bikes during racing, and all of them have been more worried about their bikes than themselves...
Can someone explain to me "on the cross-wlk of a trail"? Is that like a pedestrian crossing where bikes can cross over a road? I am just confused because over here, cars would not be on trails...
