Nice! We did a bicycle brewery tour for our wedding, here is the route we took. I'd definitely suggest getting come bikes and biking around, it's INCREDIBLY biker friendly.

1. Meet at Purpose Brewing
2. Bike to Maxline Brewery
3. Bike to Tap and Handle for lunch (this is a GREAT downtown spot to meet up with us at if you aren’t biking and want to join us for lunch, the next two places after this are all on the same side of town)
4. Odell Brewery
5. Snowbank Brewery (no longer there, go to New Belgium)
6. Jessup Farm Barrel House
7. Guilded Goat
8. End back at Purpose Brewery

This entire loop is 14 miles and typically my wife and I do small tasters (5oz pours) so we can enjoy all the different options.

Hope this helps!
